Bryton computers may good reviews as a computer. It's application may have some problems. IIRC, dcrainmaker has a couple of reviews of a couple of models. Also, I think their support is still in Taiwan, which might pose translation difficulties if you need support. When I bought a computer a few years ago, I didn't want to pay the prices for Garmin or Wahoo. I compared manuals between Lezyne, IGPSport, and Bryton and went with a Lezyne Macro which has served me well. The support has been good enough. My sensors a Blue/SC and TickrFit from Wahoo, which connect via BT. If I had it to do over, I suspect I'd have been better off with the 'Pro' model with both Ant+ and BT. For maps, the Mega XL is $200; speed, cadence, and HR from Lezyne total under $10o. For a round $100 more than the base computer price, I think you get speed, cadence, HR, and a tail light.
