Installed on my 16 flat bottom to replace the power hungry non-led lights that came with it. Its not Amazons fault that the fit is not quite as expected but to avoid a future return I think I had better visit an actual store this time. I recommend them for sure! At left, is Nike Everyday Plus. I couldnt stand them for even one minute . As expected, I think the flywheel is too light, just like most of those devices. I got a combo lifting cage with chin-up bar on the top. It was useful to me as it let me hear how loud i was being, and being a loud person it helped me shut up. Sleek design makes it a perfect addition to my desk. I tired everything in the poorly translated insructions.
