Yes, take care, that your floor has to be level ( use mats or a large piece of 5/8 to 3/4 inch thick particle board) or you will induce some form of wobble when racking the weights. Growth mindset is all about necessary program. Somewhat worth it due to the fast shipping, but for the price I feel like there?s better especially if some of the boxes are going to come broken. I bought the large size, which should be too big for me, but they fit perfectly (I normally wear a size 8). I had to add extra foam inside the default pads and had been using them this way for the entire time until these new pads came this week. They are designed for a T slot. Easy to put up. It seems when you double tap the select button itll say "battery full" and then eventually its close to empty. But I play persona 5 for hours and didnt need to charge so Im happy enough with the length. Even if NGENUITY worked, I wouldnt have a way to install it.
