I've installed a couple. My opinions are they work ok, but aren't as comfortable as my design. My design is nearly invisible to someone sitting on the seat, minus the slightly more firm seating. The edges of my design go over the frame to the end of the seat to make it not seem like your sitting in the edge of a box. I find the 33 eng box to have this feeling. I also think some 33 eng owners will argue this point unless they've set on both my and their design so don't be suprised if they post up here trying to argue.

The box works, but not as good as it could be. My box is more complicated to build but adds comfort to the seat. I also am the only one with plans for seats which do not require seat raising or raise the seat height from stock (depending on specifics to install). And again, is extended to be more comfortable.

Basically the 33 eng one works but cuts corners to speed up mass production. See my website for more information and the construction blueprints for mine if you're interested.
