I've had my "I" beam one for 3 years now. I agree with snoodsniper, the seat magnets are very weak. After opening week here in Kansas I got tired of the magnets letting the seat fall and go "thunkity, thunk, thunk" against the back of my legs in heavy brush so I retired it for now. That's the only fault I can find. Lots of room for everything and nice thick comfortable seat. I may see about using some paracord to help the magnets hold.
