Works great, amazing customer service from company

The unit that I received was totally dead, however, a message through the Amazon messaging system had a replacement on the way in a couple of days and thankfully that one was perfect.I wanted this for my spin wheel exercise bicycle.The first issue is to set the circumference of the wheel. This computer allows you to manually enter a wheel circumference, unlike so many devices that only allow a few selectable options.The next issue to be solved is that my exercise bike has a solid wheel. This meant that I would not be able to attach the magnet trigger device to a spoke as originally intended. Again, fortunately, not too difficult to solve. I was able to attach the magnet to the solid wheel by using a small amount of epoxy putty.Although the screen, and subsequently some of the text, is really very small, I am still very happy that I purchased this device. It does display and record everything that I want and for a very small amount of money.

I have just got the bike out of the garage after many years to do some exercise. The old speedo was not working and as this may be a fad and goes back in the garage did not want to spend to much. This was easy to fit has many functions. I just need distance and speed. I came across a problem that others have incurred which is when i put the LED headlight on, the screen goes blank. Google it and seems to be a common problem. It could be i have a cheap unscreened headlight or this device is cheap and has no screening to interference caused by light. I looked at some of the cures one being move both devices as far apart as possible and that worked for me. I only moved the light 2 inches. In saying that if that did not work not sure what would have done as use light in daylight nowadays.

This was the poorest bicycle computer I have had the misfortune to buy. Described by the seller as 'easy to set-up, in fact the set up was complex and inadequately explained in the instructions. Once assembled on its base for mounting on the handle bar, it had clicked into place and was impossible to separate. This matters as it makes battery replacement impossible when the need arises.The computer has to be calibrated for the exact circumference of the tyre. You have one chance to do this before the measurement is locked in: I made one mistake entering the correct digits, and discovered that the item is completely unusable. What a waste of money!

I bought this for my 5 year old grandson for his new bicycle. He loves it. He regularly shows me how many kilometers he has now ridden and also his latest speed record. It covers all the bases for a cycle computer: speed, max speed, trip distance, trip time and odometer. It was very simple to set up and seems to be accurate (checked against a much more expensive model on my bike). Very good value for money.

Unreliable. Requires constant adjustment of the wheel sensor. Often doesn't work.Updated to say seller contacted to try and resolve the issue and although that wasn't possible in this case they did offer a refund. Perhaps I got a faulty unit?

This is a great little speedometer works great give distance,speed calorie burn overall distance cycled and more . Absolutely brilliant fir the price and easy enough to install

Fantastic job until I've changed the battery and the display went tired. I went about 15 miles per hour and it shows 1.2 miles per hour. Easy to set up though, reads clearly, I could not find a setting to see my total mileage spent.
