The GPS works well and only takes a few seconds to geolocate. The unit easily connected to my bike for power and cadence. It also connected easily to my Schosche heart rate monitor.The screen is LCD and is very legible in bright sunlight. Many of the icons (GPS lock, time of day, temperature, battery level) are very small and more suited to younger eyes. The left button has three uses, on, trip start and long press for off. The screen has a backlight that is only on momentarily. After turning on you must press the left button again to start recording today's ride. You know the trip is activated by the trip time showing 1 second and holding until you start riding. The trip time is only the moving time.The right hand button toggles between prescribed pages. There are three NOW pages that show various aspects of the current ride. There is an AVERAGE page and a MAX page then the circle repeats. None of the fields can be changed to other pages.Charging is USB-C. Removing the rubber cover over the charging port is a little cumbersome. I used the direct handlebar mount rather than the handlebar extended mount. I ride rough terrain and it works well this way.GPS connects quickly. ANT connections worked easily. Seems like a good unit after a month of use. Love the USB-C port, I don't have to hunt other cords to charge. I recommend without reservation.

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.

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.

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

Great function for the price. Additional sensors make this unit very useful.

It takes 10 to 14 minutes (I tried it multiple times) after I start biking before it can connect to the internet, even though I bike in an open area and it connects in the same area, just not when I start. It does not connect to my heart rate. And no power usage report. Its report of the gradient lag is far too long; many times, it tells me that I am climbing when I’m descending and vice versa.

I immediately knew the instruments on this thing were less than highly accurate when I went outside on a 40 degree day and the temp on the screen stayed at 65. Because I had seen so many reviews about terrible accuracy, I decided to first test the device by setting it up on my dash of my car and go for a drive comparing to my speedometer. I am about 20 minutes outside of Charlotte and in a highly residential area, not in a rural area. I immediately noticed it drops signal a lot, especially under any sort of tree. The speed itself seemed accurate when working but would constantly drop to 0mph, which screws everything up. The elevation reading, also appears to be mostly useless. What it did work well for, was connecting and recording a workout from my trek duotrap ant+ sensor when using it indoors. I decided to return this thing and just by the upgraded Bluetooth version of my sensor so I can just use my phone, since the rest of the unit is basically useless. If you want to record indoor rides with an ant+ sensor, I suppose this would be fine and work well.
