I purchased this for my daughters birthday, when I was assembling it i noticed that 2 pieces (trampoline arm and screw hole) werent lined up properly and couldnt screw in.  A huge safety hazard.  I took the piece to my shop to try and flatten the base of the arm hole but I couldnt simply because its made with very cheap aluminium that could easily dent and break.  i personally wouldnt recommend it because this is made to withstand lots of jumping by kids and I dont think the construction is tested properly.  of course you can take a risk on it and buy it to see if you luck out and get 100 fit but I wouldnt.
