mounting is supposed to be with or without an extension arm. The diameter of the extension arm clamp os way too large for standard handle bar. The without option via cable ties has no saddle to sit on the handle (or was missing from mine), had to take saddle off my old redundant odometer yo use.The light doesn't work as per instructions. Instructions say should come on with button A, mine doesn't, it comes on with button B, which also changes the display info, so you hsve to cycle through all the data to get back where you were (10 functions), or set with light permanently on (obvious battery drain).The colour selection is also via button B so to change colour again it changes the display data, very anoying and making the function usless.Mine may be faulty, but hsve kept as otherwise ot works fine & looks stylish.One word of warning be sure you want the extension arm attached before clipping onto the main support plate as its impossible to remove without a screwdriver & brute force & rosk of damage.

Just need something to track time, distance and estimate calories. It's fine for that. But installation is a nightmare. The supplied extension bracket is far too big and won't fit anywhere on my bike (which is not anything unusual). The clearances on the mounting plate are very small. I did manage to use some cable ties or my own to fit it, and it works fine, so if you're a bit handy you'll be fine but the mounting on this device does clearly need a redesign, hence only three stars.

good item and battery inside item

Excellent value for money.
