The muscle memory has definitely kicked in. I had to drill pilot holes larger than I was comfortable with in order for these to go in without destroying the screw head. CONCLUSION:I would absolutely buy this seat again. I did this all summer and the sandals were completely comfortable I never had any issues with them. I then enabled the Smart Life skill using my Alexa app and connected Alexa to my Smart Life account, so i can turn them on with voice commands also. Waste of money! ) There is no "oomph" anywhere in the spectrum, they dont focus on anything in particular. The issue I had was, when reclined in my chair and turned my head, the battery/controller that hangs down is heavy and would catch on my shirt and pull the ear pieces out of my ear. The top of the shoe, before the laces have some "play". They are very hard with no cushion, however, somehow theyre still comfortable.
