Good Wireless Bike Computer for the price.

Good bike computer for speed and distance for a ride. I mostly use it to see how fast I am riding(I use an app on my phone for recording rides). Works well. Slight delay from when turning on and connection to GPS(takes a while- sometimes will be a few blocks into ride before connecting). Large screen for easy viewing.

performs basic head unit/cycling computer function

The instructions for this head unit are difficult to follow. Otherwise, it performs the basic function just fine. I was able to download the app, synch to my iphone, and also synch to an old chest strap heart monitor. So when I ride my bike I am recording my ride. It uses GPS for speed and distance. I like that a lot more than using magnets on the spokes the way the old system works. To be completely honest, this unit falls far short of other units on the market that cost 5-10x more. For the cost though this unit is fantastic. My son will use this unit for road bike training.

Great accuracy

Very happy with this bike computer. Exactly what I needed at the right price. There's no reason to spend $100 for a reliable GPS computer. That's just insane. Go with this one and you'll be happy you did.
