Seems like a pretty good system and rack so far. If you read this comment, have your nerds in slip-resistance try to improve the grip tech, because if these worked at least as well as Shoes for Crews, then these would be perfect! I read some reviews stating that these swabs were not thick enough or brittle, but I find them to be quite the opposite. This is a one-piece solution for wetting, soaping and rinsing. These are perfect and the material is high quality so we know they will last. I had only had the case for a month! a more robust low end. If this is where the future is going with sound and light then sign me up! It did have some brown streaks on the legs towards the bottom (appeared to be rust) but otherwise the quality is what I expected for the price not great but definitely not bad either. Comfort is also good but getting some ear pain after wearing continuously for >5 hours.
