I doubt any tree stand is absolutely perfect
At least mine wasn't. So I rehabed it myself. I remember soft foaming some hollow metal parts; using new solid foam for seating and back, when needed. I put on two inexpensive carry straps that improved the carry of the stand in the woods; quieted some moving parts with tape. All were improvements; did them myself.
Even though my stand wasn't perfect, I consider it an heirloom now. Wouldn't give it up for $400 and a new one. It's over 16 years old; great overall design; and was totally paid for the day I got it. The depreciation time keeps getting longer. I sure like it; only has a top weight limit of 250 lbs. Saves weight on the back.
Kind of glad I never looked for perfection.
