This was extremely easy to add to the FindMy app. I just opened FindMy, pressed the "+" to add a new item, then pressed the locator button on the card. It popped up on the screen of my phone, I named it, picked an icon and that's it. I love that it supports QI charging. Almost all the other tracker cards only have a single-use battery, so you have to replace the entire device every couple of years. This one only needs to be recharged at least once a year. There were a couple of other ones that offered recharging, but they had metal terminals on them that required you to use a proprietary charging adapter. A year from now when I would need that charging adapter, I probably would have forgotten where I placed it. With this thing I can charge it on any wireless charger, it can't be any simpler.
Please note this (and most non-Apple branded) locator devices do not use Apple's UltraWideband technology that pinpoints the device. This is good for locating the general location. You can see if you dropped your wallet in a parking lot, left it at the store, or a friend's house. Once you get there you'll have to play the chime and walk around to try and find it. Note that the UltraWideband (U1) features are only available on the iPhone 11 and newer anyway. I have an iPhone SE, which lacks the U1 chip, so all trackers, even the Apple AirTags work this way, so this isn't a big deal to me. I'm not aware of any tracker cards on the market that utilize UltraWideband technology, so as far as I can tell, this is the best card of them all.
I'll try to remember to update this review regarding the actual battery life.
