muju79 2 The main problem with this unit is ergonomics. The pull-up grip is too wide and the angle of the handles is off, making pull-ups more difficult and uncomfortable for the shoulders. This is the main problem with this unit. The second issue is that the handles only have a very thin grip cover that makes the grip again very uncomfortable, thus even worsening the main issue described above. I recommend buying protective gym gloves or additional grip covers if you don't want your hands covered in blisters in no time. The stability is acceptable but a little underwhelming. The assembly is relatively easy when done in 2 people, but the metal bars and some parts are too thin, so be careful not screwing the bolts too tightly or you'll bend the tubulars. For this price I was not expecting the same level of professional tools found in gyms, but according to the reviews here I was also expecting better than the real item. I will keep it only because I am too tired to disassemble it, and will try to make the best of it anyway but I am disappointed.
