Teasi one Extend 1673790000 Outdoor Navigation Device, Black, No

I have been looking for a device that gives me car sat nav performance on my bike, at a reasonable price and with sensible battery life. This unit is neat and fits well on the bike. The screen can be a bit reflective and needs careful positioning, but get it right and the display is clear. The touchscreen is a bit slow and not as fast as modern capacitive ones, but that is a minor quibble. The fact is that this works really well. GPS location is fast and accurate, route planning is a bit clunky on the device, but the upload from the PC is very easy. This is exactly what I wanted, the battery life is advertised at 12 hours and I get 10 hours with the screen turned up bright. Minor issues aside, this is a fab piece of kit. At the price it is remarkable.
