- Blackbox MicroSD Card Slot:
- *Betaflight firmware requires the type of microSD card to be either Standard (SDSC) or High Capacity (SDHC) under 32GB, so extended capacity cards (SDXC) are not supported (Many high-speed U3 cards are SDXC). Also, the microSD card MUST be formatted with the FAT16 or FAT32 (recommended) format. So, you could use any SD card less than 32GB, but the Betaflight can only recognize 4GB maximum. We suggest you use this 3rd party formatting tool and choose 'Overwrite format' then format your card.

Great for keeping bank statements clean but random security delays are frustrating
Reload type: One Time Reload
I use the balance reload tool to manage my monthly budget and easily hit credit card sign-up bonuses. It keeps my bank statements totally clean by grouping dozens of tiny e-book and movie rental charges into one single transaction. Most of the time the whole process works flawlessly and the money shows up in my account within five minutes. It is honestly the easiest way to put a hard limit on my family's everyday online shopping.
You just need to watch out for a few annoying system quirks when you load larger amounts of money. Even though it usually works instantly the automated security filter sometimes flags big reloads and freezes the transaction for hours. This random delay is incredibly frustrating if you are trying to add cash fast to catch a lightning deal before it expires. You also have to remember that this balance is strictly non-refundable and cannot be used to buy other gift cards.
Overall this is still a great method for organizing online spending and maximizing your cash-back credit card rewards. It totally fixed how I track household purchases but you definitely have to tolerate the occasional processing delays. My best advice is to load your account a day or two before you actually need to buy a big-ticket item. It works perfectly as a budgeting tool as long as you know the rules and plan for the random security hold.

Great for Budgeting – Instant Balance and Easy to Use
Reload type: One Time Reload
I use Amazon’s gift card reload feature to plan my spending. It’s perfect when I know I want to make a purchase but prefer to set the funds aside first.
I love that it’s immediate—no worries about pending charges or accidental spending from my card. It gives me peace of mind knowing that when I’m ready to buy, the balance is just sitting there, waiting.
Pros: easy to use, instant balance update, helps with budgeting and avoiding overspending
Cons: funds are locked into Amazon once reloaded, doesn’t count toward certain account requirements like review eligibility
Overall, it’s a convenient and reliable way to manage spending on Amazon, especially if you like having control over your purchases.

Aussie Approved
Size: Large, Color: Blue
I got a knock off one of these originally and man I should have just stuck with the real thing. My dog destroyed the other one in about 4 seconds. My dog loves this one and has not been able to tear it up, he prefers to just push it around after he gets all the treat out of it which is hilarious to watch. The quality is amazing and it is so easy to clean without leaving a smelly odor on it. It fits in my freezer perfectly and also is soft but firm so I do not have to worry about my dog hurting his teeth. For reference I have an Aussie and I got the large one which is perfect for his size (60lbs). My pet prefers this one over the last one for sure since this one actually keeps him entertained.

Awesome enrichment toy!
Size: Large, Color: Green, Size: Large, Color: Green
These are awesome! My dogs love them and keep them occupied for 30-60 mins so I can make and enjoy my coffee in peace before work. They are very easy to clean, but as others have mentioned, they can get stuck. I had to take a pliers to get one of them unscrewed. Hopefully that’s not a constant issue. I do wish they were more durable since there were a lot of teeth marks in them after the first use, so I upgraded to the black super chewer one. I’m happy I gave these a try and feel they are worth the money, especially for high energy dogs who get bored easily.

Best toy/treat! (Use oil on inner screw to open)
Size: Large, Color: Green
My dogs love these! This gives them a dedicated 20-40min of dog joy. They often get up halfway thru and switch but whatever makes them happy. They do get STUCK! And can be impossible to open. I now use a dot of olive oil on each level of the screw and then twist it in and out a couple times to distribute the lube so its possible to open when they are done. I find it very important to collect them immediately when they are done and open back up for cleaning. Do not let them dry as it will be very difficult to open.
