I bought this as it weights twice as much as the competition. It’s exceptionally well built and much sturdier then my gyms back extension. Price point is very very reasonable for what is clearly a commercial grade piece. Very impressive and a joy to use. No wobbling whatsoever and functions perfectly. Very straight forward to assemble.

Really glad I went with the M4 over the M3. Great bit of kit and being on wheels makes it really handy to move around in a small home gym setup. Would definitely recommend.
