25cm Arc Bluetooth Square Wave PCB Musical Tesla Coil Scientific Experiment Toy- US PlugFeatures:
.Desktop integrated mini solid-state Tesla coil finished product, the primary and secondary are made of PCB. It is a change from the traditional solenoid secondary Tesla coil, which is highly integrated and more clean and safe.
.The Tesla coil power supply is only 48-54V DC, and the low-voltage power supply ensures safety, and the effect is stronger than most desktop-grade commercial half-bridge Tesla coils on the market. The 2M high frequency sub-level, there is no pain even if you touch the arc with your hands.
.The 2 in 1 Tesla coil has both a toroidal coil and a coil head integrated with 6 discharge needles. Plug in the power supply and you can experience the charm of lightning in the palm.
.Bluetooth connection can play square wave music, increasing its playability. At low frequencies, you can freely play the arc between your palms. The frequency of the music mode is higher. When the arc is concentrated at one point, there will be a burning sensation.
.The power supply is a DC power adapter, no need to be grounded, it is more stable, the heat sink has a temperature control switch, the power supply has over-current protection, the pulse width of the music mode is limited, and multiple protections. There is no fan to dissipate heat (because the heat is very low), do not run at maximum power for too long, so as to avoid the temperature control protection is too fast.
.Instructions for Use: Switch down to fixed frequency mode, the knob to adjust the arc frequency and size, pause in the middle of the switch, switch up to music mode, use the audio cable to link the phone to the maximum playback, the knob can adjust the size, the right knob Control the size of the arc and twist the clockwise pointer. The left knob controls the fixed frequency frequency, and clockwise speeds up the arc spray frequency. It is best not to open the maximum arc in music mode all the time, so as to avoid the temperature control protection is too fast. If the arc in the music mode is turned to the maximum and sometimes discontinuous, this is caused by excessive power supply protection. At this time, a small arc should be opened appropriately.
.Very good science and intelligence gifts.

Asurion did what they said they would do. Couldn’t fix it so they replaced it.
My hubby cracked his 10 inch truck garmin by accident and assuring replaced it with no problems. They sent me an e-gift card and I purchased another one. I had to pay like $15 out of my pocket but it sure was better than 600.
Awesome job Asurion and thank you for the no hassel.

No hassle protection!
Twice now I've had fish finders die on me prematurely. Both were covered by Asurion, and both times they quickly got me refunded so I could get new units and get back on the water!

Excellent, prompt, zero hassle protection
I purchased a nice 3D printer for my grandson. He was thrilled and he and his dad used it frequently. The printer developed a serious problem but, thankfully, I had also purchased a three-year protection plan with Asurion. We shipped the printer to Asurion via UPS since they readily agreed to repair it or refund the purchase price. After only a few days, Asurion emailed me that the printer was not repairable. They sent me a link that enabled me to send the full purchase price to my Amazon account. I used it to purchase another printer. I am happy and my grandson is thrilled! I should add that the extended protection did not cover sales tax, nor did it cover shipping cost.

Strongly recommend
I recently used the services of this company, and I was completely satisfied. They work very professionally: whenever I reached out, they quickly resolved any issues. I strongly recommend that anyone who purchases electronic devices register their product with this insurance. It is truly reliable.

Cheap Insurance - Easy Claims Process!
I bought this warranty plan for a Dell monitor about 3.5 years ago. About a month ago, it started to give me some intermittent problems (very fast flickering & image retention). I tried everything I could to troubleshoot the issue, but it just kept coming back.
I had some issues with logging into my Asurion account because I used an EDU email, which I no longer have access to. I sent a message to Asurion here on Amazon and they sent me my plan details and everything I needed to make a claim within 24 hrs.
Once I was able to log into my account online, the claims process couldn't be faster/easier. I used the chat function and provided the rep with the issues I was having with my monitor. The rep immediately emailed me a pre-paid UPS label to send my monitor to one of their repair facilities. I got another email when my monitor was received stating that repairs could take up to 5 business days. However, the very next day I got another email stating that my monitor couldn't be repaired and they would be reimbursing me the full purchase price. I received another email with an Amazon gift card for the full price of the monitor within minutes.
This is my first experience with Asurion and I'm very impressed. The customer service is top notch. If I ever buy another expensive electronic item from Amazon, I'm definitely buying an extended warranty from Asurion.
