Bluetooth Speed & Cadence Sensors
I have a Wahoo Blue SC, but the cadence doesn't work (bought dirt cheap 2nd hand "sold as seen"). I'd like to replace it, but I don't really want to spend much money. eBay has quite a selection of unbranded/unknown brand options for pretty cheap (sub £20, mostly from China or HK) but I'm wary of risking "buy cheap, buy twice", so I have a dilemma - spend a bit more than I'd like on a recognised brand that I'm confident will work, or take a chance on the cheaper option. Does anyone here have any experience of cheap bluetooth speed & cadence sensors?
