I thought since it is a big brand it would be decent quality, WRONG! Two of the four boards used are plywood, and all boards are less than 3/4 inch thick. The other two boards are made of solid wood. A bolt hole was drilled in each corner. I oiled the reels and they spun easily. I had a specific use for it and with a few modifications it will serve my purpose. If I intended to use it to move heavy equipment I would return it. I weigh about 165 pounds and would be very hesitant to climb it! It's possible to find something of the same quality for less money at Harbor Freight!
