Ordered this because I simply wanted a wireless cycle computer that had a reasonably large display. Spotted this at £6.99 reduced from £23 (if I remember quickly). Thought it would be worth a punt and so it is. Arrived in double quick time and unless you are brain dead, it couldn't be simpler to mount/configure. Up and running in no time at all and as it happens it does much more than I would have expected for the money. Apparently it is also waterproof which has to be a good thing.
Just a tip for all those folk out there that seem to struggle when cable ties are the method of mounting. Pull these up by hand and then use a pair of pliers to go that little bit further. You'll always get one or two more extra clicks from the tie ratchet and a much tighter mounting. Good product with no complaints whatsoever. Who'd have thought it for 7 quid!
