These are good value for the money. Convenient and very much helpful. They dry out fairly quickly as well! Could be a bit sturdier but is holding the shoes fine so far. i have repurposed the cabinets to put other stuff in but now since the stuff within it isnt heavy, when i try to open the doors, the whole cabinet moves with it. Everything got wet because of the hole. I too own Kefs (The Rolls Royce of speakers) and Definity speakers, Polks, JBLs Altec Lansings, etc. I checked inside the door of the back of the speaker and BATTERY CAPACITY SAYS 7. I still wish the M1 and M2 were had 5g more tension and a tiny bit more feedback when depressed. But shame on me, for my cat got the cord AGAIN and chewed all the way through.
