Especially given the price point ($125 at time of writing) this is a phenomenal piece of equipment. Ever since I hurt my shoulder I have swapped front squats for belt squats so this gets a fair amount of use.
On the negative side, it takes a couple of minutes to set up (two things to connect to the rack, got to run a cable through the mechanism, and the two foot plates are fiddly to get seated), but on the positive side, once set up I find it to be a really nice belt squat movement. It comes with foot plates at a 10 degree angle, which serve a dual purple, they keep the mechanism in place on the floor because you're standing on them, and make the movement more quad dominated.
Would a dedicated belt squat machine be better? Almost certainly yes, but at the price point, and as something that I can store on my wall, I really like this piece of equipment.
