The QuadSend is an absolute tank. Bought as part of the Kickstarter campaign, so it came with all the bells and whistles. The main movements for Hack Squat and Leg Press feel amazing and the ROM is insane for both movements. I really like the flexibility the footplate angles to get dialed in and allow for comfortable movement patterns. I am using a lot of variation with the band pegs as well, which is a great addition you don't see on every machine.
I'll be honest that I have yet put the Leg Press Sled on the machine yet; it's simply taking up space.
