Asurion is AWESOME!
Ok, so let me start with the fact that you should NOT waste your time calling Amazon's customer service if you think you have a claim under Asurion's monthly protection plan. CALL ASURION! I wasted almost an hour with Amazon representatives that have absolutely no training in how the Asurion plan works, or even any idea if my item was covered. In fact, they told me the mechanized chair I purchased under the plan wasn't covered! Finally, my call got escalated to a manager who was just as clueless about my coverage, but had the best idea ever... call Asurion! The smartest thing I did that morning was hang up with Amazon, and reach out to Asurion as I should have done in the first place. Dealing with Asurion's customer service, after my Amazon call, was like being elevated to VIP status! 😄 Asurion's rep nicely took all my info, including the chair's purchase date and order number. Then they asked that I upload a couple of pictures of the product, along with a written description of the malfunction I had mentioned over the phone. This is where it gets really good. They told me they'd review the claim to determine if they'd send a repair specialist or reimburse me the cost of the item. In less than 48 hours, they determined that a payout was in order, and sent me an email that included an Amazon gift card for the total cost of the item minus the taxes I had paid, which I loaded directly into my Amazon wallet. Apparently, Asurion does not include the purchase taxes in their coverage. But, I can live with that. All in all, Asurion's claims division get a double thumbs up 👍🏽👍🏽, and the company gets big ups from me for not only standing behind their protection plan, but doing so expeditiously! Special note: If you buy a lot of stuff from Amazon, and have Asurion's monthly protection plan, scroll the item listing before pulling the trigger on your purchase... you need to see the green streamer that indicates your product is protected by the plan. If you don't see that, check to see if there are alternative products that might be covered. There are very few electronic or high ticket items that aren't covered, but looking for that green banner in the item description that says it's covered is key to foregoing any future headaches.

Glad to have Asurion Protection Plan!!! So easy to file a claim and get refunded!!!
I bought my ongoing protection plan about six months ago and had not used it for anything. About the same time, I purchased a small fountain for our front porch. A few weeks ago, the pump stopped working and I did everything I could think of to fix the pump, first check to see if the electrical outlet it had been plugged into still worked and it did. I then poured out all the water, added fresh water, then opened the pump to wash it out and remove any debris it had inside. There was none, and of course by now, the manufacturer's return date ended about four months ago. I was very nervous to submit a claim -- I was afraid I would get rejected, that I would have to pack up and return, or that I would be given 20 questions or more and provide mountains of paperwork to submit the claim. But it was surprisingly simple and easy, the person from Asurion was friendly and did her job incredibly well, my claim was created in their system in less than five minutes and I received a total refund minus the tax (turns out online retailer is not allowed to refund the tax because it was already paid to local and state governments. The cost of the fountain minus the tax was still about $165, which allowed me to upgrade to a much better water pump that had a higher output and also has something called "Burn Protection," ie overheating if the water level gets too low or if the pump gets plugged with debris. The total cost of the new pump was about $25 and has all kinds of amazing features as compared to the small fountain that didn't even have burn protection. I installed the new pump and it's working far better than the one that came with the fountain. Bottom line: I am so glad that I purchased the monthly protection plan from Asurion, and told my family how please I had it. They previously told me it was a waste of money and time because they wouldn't honor the claim. but they did, and I am so elated!

Stress and worry free with asurions complete protect plan
Absolutely thrilled with asurions complete protect plan. Worth every penny. My son is on the spectrum, and is very rough with devices, and I myself, am clumsy and go through devices more than the average person. Asurions comply protect plan, holds true and does exactly as promised. It feels so good to know, that next time a device breaks, I don't have to worry and stress over affording a replacement. Claims take literally 5 minutes to file, and I've not yet had an issue with anything not being covered. The only problem I ever had, was initially finding out how to contact them and file a claim. Which is simple. Don't contact Amazon, go to asurions direct website and follow the prompts. I highly recommend asurions complete protect plan, if you like removing stress from your life, and feeling a bit of security.

Worst company I’ve ever dealt with
This is probably the strongest version to use publicly because it stays factual, detailed, and angry without sounding unhinged. That’s what usually hits hardest with companies like Asurion because it reads like a documented timeline instead of just rage. I have never dealt with a more disorganized and concerning claims process in my life than what I experienced with Asurion regarding my DJI Mavic Mini Pro 5 drone claim. This entire nightmare started before the claim was even filed. For over TWO DAYS, multiple Asurion representatives insisted my product “wasn’t registered” and refused to process my claim. Meanwhile, Asurion’s own phone system literally states: “Great news, you no longer have to register your products.” Their own employees did not understand how their own system worked. I was transferred endlessly between departments, hung up on repeatedly, and even sent to Amazon support despite Amazon having nothing to do with the issue. It finally took speaking to a supervisor on the THIRD DAY for someone to admit they were wrong and manually file the claim. I mailed my drone on May 4th regarding a serious GPS/compass issue where the drone would unexpectedly drift or take off on its own while recording. Considering this is a nearly $2,000 flying device, this was obviously a major safety concern. Then things somehow got worse. On May 5th — less than 24 hours after receiving the drone — I got an email saying it had already shipped back to me. No repair details. No explanation. Nothing. When I called asking what repairs were actually performed, supervisor “CES” told me there were “no notes” explaining what had been done. She promised she would investigate personally and call me back within 24 hours. She never called back. On May 8th, after following up myself, another supervisor finally stated that the technician had “soldered/re-soldered” something on the drone. No explanation of WHAT was soldered. No detailed repair notes. No documentation. Nothing. This is a drone that had ZERO physical damage and had NEVER been crashed. I asked for written documentation of the repairs and was refused. I was told to “check the portal,” even though the portal contained absolutely no repair information whatsoever. Another supervisor apologized and promised to email me detailed information immediately. That never happened either. At this point, multiple supervisors had promised callbacks, documentation, and escalation reviews — and not a single one followed through. The drone arrived back while I was still on the phone with Asurion. I powered it on and immediately received compass calibration errors. The drone would not properly calibrate. So after all this, the drone STILL had issues. Instead of taking accountability, supervisor “Ryan” accused me of “chasing a reimbursement check,” which is insane considering Asurion themselves only offer two resolutions: repair or reimbursement. He repeatedly insisted that because I “received a service,” the issue was basically over. He refused to acknowledge my concerns regarding undocumented soldering repairs on a nearly $2,000 aircraft and ultimately hung up on me. Since then, the situation has only become more absurd. Some supervisors told me the situation was unacceptable and assured me I would likely be reimbursed if I mailed the drone back. Others told me they needed more photos, receipts, and serial numbers — despite the fact that all of this had already been submitted previously and somehow “disappeared” from their system. One representative demanded photos of a serial number physically located on the drone itself. I explained that DJI stores the serial information digitally through the controller/settings, something Asurion should absolutely know if they repair DJI drones professionally. That representative then refused to help me further and hung up. Days later, another representative suddenly approved a return shipping label anyway, making all the previous arguments and delays completely pointless. Now, after weeks of this chaos, I’ve been told by another supervisor not to even send the drone back yet because they “aren’t sure what they’re going to do.” I was explicitly told they may not repair it and may not reimburse it either. So to summarize: * Asurion employees didn’t understand their own registration system. * I was repeatedly hung up on and transferred around. * Multiple supervisors promised callbacks and never followed through. * My nearly $2,000 drone was “repaired” in under 24 hours with vague undocumented soldering work. * Nobody can tell me exactly what was repaired. * The drone still had calibration issues immediately after return. * Supervisors contradicted each other constantly. * Previously submitted documents mysteriously disappeared. * I was accused of “chasing a check” for wanting accountability regarding a failed repair. * I still don’t know whether they plan to repair, reimburse, or do nothing. This has been one of the most frustrating, unprofessional, and concerning customer service experiences I have ever dealt with.

Fantastic Product
Size: 13"-27", Style: Single, Size: 13"-27", Style: Single
The Wali Single Monitor Desk Mount works better than I expected. First, the basics. The mount comes well packed and the instructions are very simple to understand. There is so little assembly required that the instructions are almost not needed. Assembly and installation can be done in less than ten minutes (not including cable management if you choose to use that feature). Adjusting everything is easy. Overall quality of the parts and the assembled product are quite good. I have two monitors that I wanted to mount on a flat desktop. I needed to be able to get the monitors right next to each other and still have the desk flat against the wall. Most double monitor stands will not allow for this unless your monitors are the perfect size for the spread of the arms. The movable arms will usually flex toward the wall if you want the monitors to be edge-to-edge with each other. The result is the desk having to be offset from the wall to accommodate this. By using two single monitor stands, I am able to move the posts to positions that allow the arms to be extended in such a way that everything is flat with the wall. The other frequently stated issue with most monitor stands is that the arms have hydraulic pistons and/or springs to deal with the weight of the attached monitors so they are easy to move up and down. These pistons and springs are often of poor quality and either fail quickly or don't work as expected from the get-go. This is not a problem with the Wali Single Monitor Desk Mount. The arm is solidly attached to the 16" pole and only moves up and down by loosening the arm mounting and sliding the arm up or down on the pole. The arm, once set to the desired height, can be move forward, backward, side-to-side and tilt. This makes for a much sturdier setup with no pistons or springs. This system works very well, since I (and I think most people) have little need to move a monitor up or down after the initial installation. I leave the included Allen wrench stuck in one of the vertical facing screws behind a monitor so that it is always handy but out of sight. If I do need to move the monitors up or down, the tool is right there. I will buy two more of these for my wife's desk.
