I like how compact and quiet this squat machine is. The band tension is good and I can definitely feel my muscles working after a few reps. I started with all three bands, but switched to two in order to do more reps without working my knees too much. I'm hoping that my knees and core will feel stronger with consistent use. I've been trying to stay in the habit of squeezing my core, glutes, and thighs and pushing my heels down into the pedals to prevent knee strain, which seems to be working well for me. Overall, assembly was straightforward, it's compact, adjustable, decently light, and feels sturdy.
