I've had these for about 2 years now, picked them up on an amazon black friday clearance deal for around $60. I got them thinking I'd get into oly lifts. Turns out I do this about once a year until I realize I hate oly lifts, so these collect dust. They do work, do prevent noise, etc. I build a small wooden platform to put in between them so that it was even for DLs but I also have titan tiles which protect the floor just as well. Only thing I dont like about crash pads is they aren't the easiest to load and the do sink a bit when loaded.
