No complaints. The grip keeps my feet from sliding and the curve allows for a great stretch.

With over 400lbs in digital resistance, this gets the job done. The build quality is great. If the software was a good as the hardware this company wouldn't be on the verge of closing. The software works but the app needs refinement. Other than that the only issue with this is it's not possible to do any pull down movements.

This machine is great. I bought this over a rack because I thought it would be safer for me when working out alone and for my children as they become interested in lifting. I can push to or close to failure without any fear of needing to dump the weight. The machine takes up a relatively small amount of space, considering it's versatility. There are few exercises that cannot be performed with the QFT. The vast majority of movements feel really good. The more I use it the more efficient my workouts become. At first it takes time to figure out where things feel the best but after 2 months of use I at pretty locked in to my current training movements. The build quality is solid, I believe this machine will outlast me. The owner, Glen, is great. He responds quickly to emails and seems passionate about his machine and resistance training in general.
