Constant device disconnects renders it unusable
Device detected on USB but reader interface never initializes. PC/SC repeatedly fails with LIBUSB timeouts. Unable to use device despite resets and power cycling. Likely defective. Would not recommend.

Product works great have not had any issues
This thing's been wonderful, bought it to write RFID tags for my 3D printing spools, works awesome. Only thing is I need to find a program that works with it so that I can write tags for other things such as luggage tags and things like that

One of those things that sucks to learn but once you get it… it’s easy.
Okay, so the product DOES work despite all the terrible reviews. BUT yes the software a bit cryptic alongside the directions. Since there are many different files & whatnot. One of the PDF’s contains the most amount of info that helps the most at explaining what needs to be done. When I set mine up I found that when you connect, choosing “Shared” “T1” allowed me to write to NFC technology (that’s my sole use case). When looking at the directions I tried to ‘quick search’ the differences between T1 T0… no docs explained them nor for Shared or the other options which I am drawing blank as we speak. I am personally calling this product cryptic maybe because I do not fully understand its other use cases which makes me more ignorant than helpful but as I said, my sole use is for NFC & it works for NFC. Once you get it to work fully it’s easier to repeat for additional use. Overall, it’s not a bad product but they should provide video tutorials for the slower customers who are new at this (me). I’d agree for value for money since it’s one of the cheaper options & it reads cards very well. NOTE!! The 3 cards they send are NOT NFC.. I think they are just PVC which contains no technology so when you read the comments saying it’s doesn’t read, they are trying their own. I know this for sure because iPhone App Store has a NFC card read/writer app that I used which has been able to read every nfc piece of tech I have until those blank cards they send. Word of advice: DO NOT SEND THOSE BLANK CARDS!!!

Works great!
Plugged into PC, installed NFC TOOLS write all 3 of the cards with a URL and tested all phones read them straight away. Bought some little sticker disks and they also all worked! Perfect! Having said that I did not know that my pixel 9 pro also writes cards and tags but it's nice to have a PC option.
