I've had this cage in my home gym for about 2 years now. Overall I'm very happy with it. For the price it covers everything it needs to.
There is one really obvious improvement that could be made which is to add additional higher holes for the hooks (as mentioned in a previous review). Like the other reviewed I've resorted to adding an additional set of holes myself for squatting. The highest available holes when it comes out of the factory are just too low for most people.
I also use it now without the pull up bar as I got sick of bumping my head on it. I'm sure removing this wouldn't be recommended, and I'm not making a recommendation to do so, but it feels solid as a rock with the weights I lift so I'm happy to continue this way.
Overall would recommend, but please SS, do the obvious and add higher holes!
