    I’ve ridden with this computer on my bike at the same time I have both strava, ride with gps, and a wheel mounted by computer. Those three all are in strong agreement with each other but this computer simply does not report accurate distance or speed. No matter what changes I’ve made to it, it is up to 20% high or 20% low. The vendor offers no support for correction of this issue, simply telling me repeatedly that this brand new computer needs a firmware update or I need to ride someplace where there aren’t trees. Do not waste your money.

    I’m not tech savvy so install and set up was a bit challenging. I am certain that I set my wheel size properly. Once installed, the readout was partially faded out. I need to work on settings because it was showing about 4 to 5 miles greater than actual on a 25 mile ride. I bought it because I want basic info, current and averages for speed , distance and current pace.
    Update: still unable to get accurate distances after numerous attempts. Today after I hit a bump, it added 2 miles to my distance instantly. WTF? Not worth the purchase.

    I bought a rockbros HRM and connected it flawlessly. I bought a crank power meter, for Shimano 105, and connected it flawlessly. Cadence and speed sensors all hooked up easily. I just used it to ride a one day, 150 miles across Michigan and everything worked perfectly. For the price, you can’t go wrong. I mounted it in a Garmin-type our front adapter with a place underneath for a light. I bought the inexpensive after market adapter for my NiteRider Lumina 900 and I’m amazed at how much functionality I now have on a very small bit of handlebar real estate.

    Don’t buy it. It’s not easy to setup. The speedometer and the distance is not accurate at all. The distance reader goes so fast.

    The display is clear for day and night use. The screen is always lit. It is bluetooth so it can connect to your phone and strava. Only difference is it will not show your heart rate and calories burned when logging in data to strava.

    Setting up was a bit difficult. I used youtube to help. But once you get it down its as accurate as it can get.

    As far as accuracy. The mph is off just slightly but not too much. Example: apple watch says 15 mph and computer shows 14.7 mph. Distance travelled apple watch shows 30 miles traveled, computer showed 29.1 miles traveled.

    So cant complain
