Hey Heeze, I also have the older model treelounge with the square tube, and have been using it for about 10 years with much success and happiness. I have used other climbers, and have another brand climber, but it very seldom gets used 'cause I prefer the safety and comfort of the treelounge. I wouldn't trade or sell mine for anything short of three times what I paid for it! It's improved my hunting success by 100%.
