The Allflex LPR came frustratingly close to being the perfect reader...it's my personal favourite for form factor, read range and battery life are really good and it's sturdy as all-get-out.
But like the GPR+, that's where the fun stops. Connection is again sub-par, for whatever reason the first read would always send through partial tag number and the read button itself is terrible. It's flat to the touch, so you can't locate it without looking at the device and the material wore out quite quickly.
By default the time-out is 90sec which is waaaaaay too short and you need access to a Windows computer with some technical chops to figure out how to change that. The LPR was the worst for connection / reconnection in my experience, errors ranged from not connecting at all to getting stuck and remaining connected to the phone until it went flat. Unfortunately the battery is not easily accessible, and with the lack of a hard reset button this device didn't stay in my rotation very long.
Like most devices using older Bluetooth implementations, it's not good at swapping between phones so I cannot recommend this device for multi-employee environments.
