Not realizing it came with a set of feet already, I ordered a set of square, clear feet to protect it from moisture that it might pick up from the countertop in the event of a spill, and they do a very nice job. I have tried cheaper sandals in shops and the difference is obvious to me straight away. 3) Its May 15th, so almost 3 whole months since I purchased these. The hook is still secure in my shower regardless of the water. If you have sensitive feet you may want to think twice. These are not as thick as the stock ear pads which reduces the clamping force. The second game is a memory game like Simon but the beep sounds are all the same, and not pleasant, which is the critical element that makes Simon fun and melodic. I didnt notice that the pair I have is a 400 model and the ones that were delivered today are a 600 model. Not to mention a replacement was the price of a brand new controller! I bought these for my one year old niece who loves the Bubble Guppies.
