The HTC Fetch isn't new for the HTC 10, but it's an amazing little accessory for those who have tried it. If you're like me and constantly lose your phone, the HTC Fetch will be your best friend.
Attach it to your keychain or purse, then just press the button and the compact keychain device activates your phone’s ringtone within 15 meters. Pair it with your phone and you’ll get a warning beep if you leave it behind. If you lose both, a convenient map location feature lets you know where your HTC Fetch and phone were last together.
Owners will get an audio beep if they leave their phone behind, so you won't lose or forget it at a bar, and when it's lost it cranks up the volume to help owners find their lost device. It's a nice little accessory that debuted for $29.99, but can be found for under $10 these days.
