After owning 2 indoor home pull up/dip stations, this one is the most sturdy and stable I have owned. I have it set up outside on my concrete back yard patio and it is stable enough for what I use it for that I don't need to bolt it down. I lined the bottom with rubber garage door weather seal. I weigh 165 lbs. and use it regularly for weighted pull ups and dips, hanging leg/knee raises, toe to bar, windshield wipers, and oblique abdominal sit ups. However, if you plan on performing any plyometric exercises on it that require you to change your grips mid-air, then you should definitely bolt it down.
As for the height, I'm 5'10" and it works fine for me. If you're over 6 feet, it might seem short if you do hanging leg/knee raises or pull ups (you would have to keep your knees bent).
The only minor issues I had was that the shipping box came pretty beat up and some of the pieces came with a few scratches/chips. Also, the black caps were the only pieces that didn't seem to fit "perfectly." They fit okay, but they kind of pop out a little occasionally. The diameter of the pull up bar is thicker than the typical ones you find in gyms and parks, which makes it more challenging, but I consider that a good thing. Keep in mind, this product does not have bars for neutral grip pull ups.
The directions were clear and assembly was easy (all of the pieces/bolts fit well, I was able to hand tighten everything at first and then used the allen key to tighten everything at the end). As the directions say, don't tighten anything until the last step.
Overall, I'm very satisfied with the product. I no longer need to lug my pull/dip chain belt and weight vest to the park to do my workouts and I can keep it outside with taking up indoor space.
Great product, paint is iffy. Two of the pieces i received had scratches and rust. another piece has a small amount. the company quickly swapped the pieces. I think to keep this thing from rusting, you should it every so often.
Just got it assembled and wow - this thing is for real. Didn't rock at all or budge when I did some dips and pullups. I can see it lasting for a very long time.
Perfect tool for workout on my deck. I bought a storage bench for dumbbells and can perform a high intensity interval training (HIIT) workout on my deck, checkout MAX WORKOUT website for HIIT workout to get lean!!!!
Really good power tower! Installation was not hard, everything allied pretty well. The only thing I wish it had is an opportunity to extend it's height. I am not a fan of pull ups with bended knees.
