I have now used it for 6 months with zero issues. This mouse features a new stabilization method for the M3 where the click is in line and behind the scroll wheel instead of to the side. Sandals fit fine. Putting it together: came with the bolts secured in the spots they go. Closed toe shoes and peep toes work best but you can be clever with all others. It took quite a while to get used to the product. Time will tell as I will use these as my water sandals. For 25 bucks, these things are a steal! Usually a single or two racks stacked do not provide enough space for a whole family to place shoes. I am a tried and true size 7 wide width.
