Good quality

These were beautifully packed and all 50 were there. They are credit card size and feel but smooth shiny and clear transparent. They feel stiff and really excellent quality. The chip and aerial do not impact the surface. I chose transparent, as it makes it a bit clearer that there IS something NFC scanable inside (not just white plastic) and they could be put over or under stickers and writing.Just one random one tested so far and it works nicely rewriting as expected of a NTAG215 BUT it is reported as a cloned chip rather than a NXP genuine article. Whether this matters, only time will tell.The scan distance is about 1.5cm with my phone. You will understand they are NOT anti-metal as expected, since there is no ability to put such a layer in a clear tag.I plan to test these for ruggedness / outside use (one potential use case for me) by immersion, sunlight and then one will have a go through a washing machine. It will be interesting to see if it delaminates etc. I will try the dushwasher and freezer too. I'm not yet sure of an upper thermal range. I will probably try 50°C water. But these ruggedness tests are unfair if you just plan normal use.A 215 gives a generous capacity ~500 bytes for most URL use and so I may not need a URL shortener in the way that a QR code alternative would need.Overall Impression:- Excellent quality and feel for the price. Now I must press them into service.

Very good

If you're looking for NFC tags these are perfect.

Doesn’t work with iPhone. It wasn’t clear when I purchased so for me it is not usable. But it would be a good gadget if it would work with iPhone.

Work great with TagMo

Not compatible with yoto as implied
