and because the set I received has some cosmetic defects (not a big deal). My main complaint about these is that the case can be surprisingly hard to open. Unfortunately they?ve started to come adrift after only 2 weeks of wearing them! Finally the battery play time is about 6 hours instead of the stated time in the spec. If you were to buy this belt by itself with nothing to compare it to, it feels great right off the bat. They keyboard is brand new, so there should be no dirt or dust in the keys. Best to choose. The crochet band straps are very comfortable on my average, medium width feet. Also it is a big plus that the cover has four ties at the bottom which can be easily tied up with the rack. It took me a couple of tries to discover that a Size 7 is what I need in this brand.
