The vest works fine, it heats pretty good. The only downside is that there is too few heating zones, and no heating in chest area at all. The sizing is also wrong, sizes are too small (For me 186cm and 85kg XXXL fits ok)
good material good quality... but there are just 2 heating pads on the back. (not 3 as shown) all hesting pads are very small. heating well... getting really warm around 50 on full speed .. smells very bad.
