Very good for the price. I like tge fact there is no monthly price, you have to move around to catch the signal as walls block it but it,s ok for local loss.
Opted for these because of price and exchangable battery. I suppose i was expecting better coverage. The garage is already out of reach. The "lost" mode is pretty much useless if no one has the chipolo app. I wish there was coverage through other carriers (Samsung, Motorola etc...) so that there actually would be a chance of finding the lost item for Android based Tags.
Bought the pack and it's been great but 1 of the 4 trackers I bought constantly pings that it lost signal while at home and that I've forgotten my keys which is kind of annoying.
4 pack of key Chipolo arrived extremely well packed and quickly. Had an issue with one being over jealous with the missing alert but have to say that real people seem to contact with advice to correctly resolve.
I had a Chipolo tag years ago and bought a Tile, then a Samsung tag just to see what they were like. Back with Chipolo again. It's just more consistent than the other two and I feel I can trust it to find my keys when I need to! The same can't be said of the Tile and Samsung tag I used!
