Couldn't justify a really expensive cycle computer as I only wanted basic tracking. It matched Strava stats so seemed quite accurate although it didn't link up, not sure if it was supposed to? Anyway can't grumble, did well.

Very good item I’m pleased with it

Exactly what I needed for my bike.

Easy to install and I’m a muppet at these things. Also it has yet to fail on a pan European ride. Impressed!

This product was a waste of my time. The shipping and delivery aspect was great as always however the product, useless.Very basic instructions which to be honest could have been a lot better and a lot clearer.Once I finally set it up the sensor which reads the magnet doesn’t even work. Tried multiple batteries. Tried aligning the magnet and sensor multiple times in multiple different ways none work.Don’t waste your time with this I would say go with an amazon recommended product so you a least know the product has been reviewed properly and you never know it might actually work

The listing suggests that this works with GPS (Global positioning satellite). It doesn't - uses a magnet on the bike's wheel. Thought it was too cheap to be true and was once again proved right.
