I bought the $100 Bryton Gardia (Varia competitor) - Ask me anything

I don't think we know whether it works yet. The fact that it lost sight of a car for a few seconds over a hill and then didn't alert you again is concerning. In my area that kind of thing happens multiple times every ride and a Garmin handles it flawlessly. A radar has to be pretty darn close to 100% reliable to be worth anything at all.

I agree that this is not a component on which I'd prioritize saving money. Especially considering that $50-100 is insignificant relative to what most people on a board like this spend on cycling in total.
