I can't speak for every review out there, but I know this tower is commonly not installed 100% correct. I had that tower on my Tige and when I bought the boat, it did not have the bolts installed at the rear upper joints. There is a large bolt going through the center and once everything is set up and installed, there are additional bolts that are to be installed to make everything solid so it does not tweak side to side. I have literally seen boats being trailered down the highway with these lopsided monster towers... its due to incomplete installation.
I enjoyed the tower and it was easy to fold down and put up. Heck... I cant even get the pins in on my illusion tower without someones assistance.
