Which brings me to my next pain-point. Ease of assembly not so much although it appeared easy. The brush will feel a little rough but I like that personally cuz it feels like all that top layer of dead skin comes off more easily than with a loofah. Typically, after breakfast I will sit down and fill enough for the weekend. They were pretty easy to install, just pushing in the plastic clips until its snug, and turning my headphones one. They have also developed an in ear connection issue so that sometimes sound only comes through 1 ear instead of both or is static filled (something I expect of cheap wired earphones, not expensive wireless ones). The ear pads had excellent instructions on installing them. They are much thinner and much more stiff, which leads it to be much less comfortable. These fit well, keep your feet warm but not hot but mine wore through at the toes in just 4 months! However, for some reason, the left shoe is slightly smaller.
