Just bought this to put in the shed to see if it’s any good with Absorbing any moisture like it boasts. Might be useful if you have bikes in a cold damp garage or shed. Not sure if it will be any good but worth a try as Tesco are currently selling them for half price. I guess even if it helps a little it’s better than nothing and needs no power to make it work. Will post an update in a few days to see if it’s captured any moisture.
