Great product and helpful features!
I genuinely love this product and the seller is so nice! I got the 128 GB Flash Drive with detailed instructions, a very nice card from the company and three free stickers! It also came with a small band to use to attach to a clip or something to make it easy to be portable. It also has protectors over the ports which I thought was a nice touch and it even came with an extra cover for each port. It worked out great for me and the app was easy to use. Although if you are trying to move a lot of photos I suggest in batches otherwise it takes hours lol

Unexpected surprise in quality and fun.
Instructions are clear. Flash Drive is excellent quality; made of a durable metal really solid. Not plastic,It has extra end caps and a small carry attachment ( which personally I love) can clip and go . Made for Apple products. Comes with a thank you and cute stickers . Speaks volumes about the personality and care of the seller. Didn’t cost a bundle like most Apple products, storage seems good and ease of use seems easy..several options in color . For value personally this is a winner even if you don’t care about cost the quality is a notch above

Decent Adapter With Few Drawbacks
So after using this for about a month now, I can confidently say that this is a fairly solid product with very few drawbacks. For context, my setup is in a pretty crappy spot. I’m on the second floor with my PC tucked between my desk and dresser all inside of my bedroom closet, so I’m sure you can imagine how difficult it is to get a decently strong connection. The previous WiFi adapter I had only got me a messily 50-60 mbps download speed which was barely enough to watch a YouTube video. God forbid I try to download something or play an online game without having to wait hours for it to load or finish though. I’m fairly new to the PC world and didn’t do much research so it was my fault for getting a weak first adapter. Luckily after figuring out what I actually needed, I stumbled across this one and decided to try it out. It supposedly offered high download speeds, a good reception, and was cheaper than most other adapters with the same features, so I went ahead and bought it. After plugging it in with the platform extension, it connected immediately and started searching for wifi networks to connect to. I tried downloading the drivers with the usb it came with but it wouldn’t connect for some reason so I gave up on trying, either way, it still works perfectly fine. After connecting to my wifi I saw a HUGE difference. I jumped from 50 mbps to a little over 200 as you can see in the pictures. I could finally use my PC as it was intended and I never have to worry about slow speeds or not being able to play certain online games. Now there are a few drawbacks as I mentioned, none that are super bad but it was worth taking 1 star off IMO. One drawback has to do with the base extension. You’re not allowed to use it on any of your front USB adapters and I quickly learned why. It overheats the adapter and short circuits itself and the PC. At one point I heard a slight hum and some popping sounds and my PC would start to flicker off and on, so that wasn’t good at all. Given my setup, having it in the front makes it more convenient for me as I was able to put the adapter in a slightly better position, but since I have to use the back, it shortens the length of the wire and restricts where I can actually place it so that kind of sucked, but not a huge issue. Another thing with the base extension is that it doesn’t securely hold the adapter. Sometimes I’ll accidentally brush against the antenna or if my PC shakes the adapter loses connection with the base and the internet goes out. It’s kind of annoying b/c just the tiniest movement to it will lose the connection and I’ll have to wait a minute for it to reboot itself. Again, not the biggest deal and is probably only an issue b/c of my setup, so this might not really bother others, but I thought I’d point it out anyways. Overall though, I’d recommend this product. It has risen about 10 bucks from when I bought it though (26 to 36 bucks), but even at this new price, it still beats other adapters going for around 20 to 30 bucks more for the same speeds and hardware. If you need something decent with a pretty reliable connection, aside from the base extension issues, then go ahead and buy this, it’ll be worth the money.

Plug-and-play. No hard setup.
If this device cost twice what I paid for it, I’d happily pay double. No need to link to a desktop or a laptop. Simply plug the device into your phone, and you are prompted to download an app. You don’t need to sign up or anything within the app. Photos start downloading as soon as you hit the app’s backup button. Outstanding product.

Worth it must try!!!
I was trying to look for a flash drive that can be use for pc and for phone (specifically for iphone) and came across with the product did i've seen mixed review with this product and for my opinion. This is the product to have I got the 128gb just to test it out and I'm not expecting it is compatible with PC, Laptop, Android phone & tablet. Not to mention it even works with iphones as well, I got the 16 series and my extra phone iphone 12 series & XS Max all of them does work with this USB flash drive for 12 series and XS Max you need to download an app from apple store named U Disk its a free app it will automatically tell you if it does not support plug and play you'll get a pop up that tells you to download the app when you plug the drive. But for Iphone 16 series its basically plug and play. This is a must have for portable storage for your pictures videos and other types of files, data transfer is fast. It does come with instruction manual & some cute stickers, Great stability & quality is well built. I definetly recommend this product if you are looking for a flash drive that works on any device. My product review is proven. I rarely do a review with products but this do satisfy me on how well it works. And its worth every penny. Will pick this product incase I want to buy more!!. Keep up the good work!!

Impressed do far
I just received this so I have not used it yet but I was really impressed with the package not only was it in a very nice box but put together with a smile. There was a very nice thank you card and three adorable stickers that you couldn’t help but make you smile when you see them. There is a nice strap you can attach which I myself love. I can only imagine it will work exactly like I’m hoping but so far I most definitely approve of this purchase.

I've been working from home for a year now, and only recently I brought home my work computer (desktop). Because it doesn't have a wifi card in it, it was recommended by our IT guy to get this adapter. I was skeptical at first but got it. It works great, I thought my wifi wasn't going to be stable enough to sustain the connection, but it hasn't let me down. Haven't had the opportunity to use their tech support because I haven't had any problems with it, which is a good thing.

Funciona segun las caracteristicas do fabricante. Trabajo con videos y utilizo para enviar y recibir más de 10/día de ficheros de 3 a 5 Gb. Lo unico que veo de malo es que se calienta más de lo normal y por ser de plástico, la disipación de calor se ve reducida. Pero hasta ahora doy mucha caña y tiene aguantado. Me resuelve por la ganancia del señal de donde estoy en un rincón apartado... Recomiendo!

I bought this for my Dad. He said it was fantastic - easy to set up in just a few minutes, and then he had WiFi in his office which is 20 metres from the house, which was just as good as the WiFi in the house.
