Can’t fault it
Having ridden with power for a long time I wanted a cheap power meter for one of my bikes I wasn’t fussed about it being single sided. Fitting is simple and calibrating using the app was easy. Having now used it for well over a month most days I can say it’s reliable and the figures are pretty stable I haven’t used it in the winter yet or rain but no issues with connection and seems like a solid unit only time will tell but for the money it’s perfect unless your pro buy one off these
