Garbage doesn't work Once paired with the dongle, the first time you move away from the PC it is locked correctly. From then on the PC fails to unlock despite the phone being right next to the PC. Unpaired the phone and went back to using the tag.

Hello Mark! We're sorry to hear about your unpleasant experience. When using the GateKeeper since we cannot control the Bluetooth signal of the phone it is really important to keep the device in the direct line of sight of the USB dongle. We also recommend updating the Android to v7.0 for better performance.

Hello Derek, We have released the 1.9 version of the Trident app. This app when used with the latest version of the GateKeeper software improves the signal quality and eliminates the inconsistency in locking your computer. Please upgrade to the latest version (3.7.10) of the GateKeeper Windows software for optimal performance. Thanks. GateKeeper

Functional, but locks my computer like 3-8 times a day for no reason (tested both their Bluetooth dongle and my Bluetooth with 16db antenna, phone right nearby)
