I got my first tiles as gifts and then decided to buy more for myself. Absolutely would reccomend compared to the other stuff out there I've had the best results with Tile. I mean I use this stuff almost everyday to find keys, wallet you name it I'm looking for it.
I haven't used the new stickers and sizes that have come out recently surprisingly I haven't lost my orginal tiles so maybe I'm getting better about not losing things haha.
The only downside that i've experienced is just when you go out of range and the location on the map seems wonky at times but overall it does what it promises.
