Good quality and value, but need 2 wrenches to assemble. Only one “wrenchette” is included.

I bought this set for my jumping exercises. The product seems to have some minor packing issues: the parts were not tied very well in place in the shipping box and the shipping box opened a small hole. Also, one of the jumping boxes twisted a little bit. But this was no big deal, I solved it easily with a rubber hammer.After I finally assembled the set; they looked very good. So far I only used two boxes; I felt they both very stable and held my landing momentum very well. All in all this is a very good product set and serves my need very well. If you don't worry about the possible packing issue, go for it!One caution: the boxes slip a little bit on my vinyl floor. After I put a rubber pad underneath the boxes, no slips any more.

Was missing a piece upon delivery but they were quick to send out a replacement.

Assembly wasn't as easy as I would have thought. A couple hard to reach places. But just bust out your ratchet and you'll be good to go.Anyway, just started jumping on the 30" one yesterday and man, my ABS are sore. Great workout.We'll see how stable they are after a few months of use but so far, I love these things,

Product was easy to assemble. Well built and sturdy. Would recommend to anyone. Edward Collins.

All in all does exactly what we needed for the home gym. The only negative is you have to unstack them to get the smaller ones out of the bottom instead of being able to slide out of the stack.. not a big deal though

The jump box was easy to assemble and it's extremely sturdy. I weigh 235 pounds and it supports my weight with no issues. The anti-skid rubber surface also gives me added reassurance that I won't slip off the box when using it. And the open space inside the box frame provides a great space for storing free weights and other gym equipment in my home gym. Overall, I give this product an A+! --Drew Stewart

Easy to move around and perfect height for a variety of workout needs

Solid. No issues with jumping up onto the box or stepping up for pull ups. Sturdy and good quality.

Love the bench! However, missing one bolt (received the screw), so one corner is not secure.
