It's great, BUT
This device has a separation alarm, which you cannot find with Tile or the other item locaters. The only reason I have this device is for the separation alarm. If I walk away from my keys, my phone makes an audible signal, if I walk away from my phone, my keys make an audible signal. This feature works for me 100% of the time. It has never failed yet and I have had this Youduo Retrivr 2 key finder (key fob) since November 6, 2017. What's not to love about this device? I talked about this device so lovingly that one of my friends got it also. He threw it away the first week he had it. It gave too many false separations (the phone will sound an alert with the keys right next to it). I have an iphone and he has an android. I would buy this device again and again. I highly recommend it. Now for some secondary issues: (1) Loudness: the phone is perfect, the keys are quiet but adequate. (2) Calling the other device: both call each other without fail. I rarely use this feature but it is very useful when you need it. I have found my keys in the door, I have found my phone bundled up in the bedsheets. Great feature when you need it. (3) The button on the the key fob is easily pressed by keys in your pocket so I superglued a round piece of a Dixie plastic cup over the top of the button. Now I can still press the button if I press it with my thumbnail real hard. (4) Long range: you don't need long range. This device is only for those short range times when you walk away from either your keys or your phone. (5) Battery life. EXCELLENT. The same battery lasted from 11-6-17 till today 2-13-18. The battery indicator on the phone shows 25% and a couple of false separations this week prompted me to change the battery, which led me to writing this review. (6) Bluetooth always on: This is not a problem but has led to a related problem which is nothing compared to losing your phone or keys. The problem is when you turn on airplane mode, both the phone and keys instantly start sounding. So do NOT turn on airplane mode in the middle of a meeting. Getting everything shut down and quiet is VERY embarrassing :-)It's alright
The device is alright but not long range at all and has to be Bluetooth connected at all times or you won't know where it is.. I wouldn't buy again
