This is a really good bike gadget. It arrived quickly, was very easy to fit and works well. The screen is clear and not too complicated. I've used it now for several weeks in sunshine and rain with no problems. Excxellent value for money.
At this price the bottle and cage looked worth buying. The cage was easy to fit and the bottle looked good. However the water in the bottle still has a strong plastic taste despite many attempts to rinse it out. I've now bought a replacement bottle and use this one as a spare.
