Review: Solid build. - Very sturdy and adjusts well. My junior high athlete uses this at its highest setting often. I don't have any concerns about it collapsing. It is a bit heavy. However, it seems like a solid build.
Review: Great Quality and is a good elevated work platform - I just bought this and used it a few time but so far it's great. The quality really is fantastic and I don't think I'll ever have to buy another Plyo box. The paint quality is good, I didn't have any scratches/nicks/ or missed spots on mine. So far I've used this box for jumps-great, doesn't move/slip, and the rubber top surface has some cushion, and isn't slippery, elevated push-ups, stretching, etc-pretty good, the sides don't have any sharp surfaces so you won't cut yourself. Only possible complaint here is there isn't a lot of room to grab on the sides because of the sliding mechanism for the legs...not really a big problem just wanted to let others know. I also was doing some plumbing in the basement and just need to be up a step or two...this is way better then a ladder because you can walk around a bit so I wasn't constantly moving a ladder. Overall I'm very happy with this and would recommend it to anyone looking for a high quality adjustable Plyo box. The legs aren't hard to adjust but take a little getting used to. I wouldn't want to do a workout and change the height a bunch of times throughout the workout, so the only possible way I wouldn't buy this is if I was doing a workout that needed multiple Plyo box heights in each session, then I'd probably buy a dedicated height set. I was going to build my own multiple height wooden box and am very happy I decided against doing that.

### ⭐⭐⭐⭐⭐ High Quality Plyo Box
*by C***E on May 28, 2019*

After researching several plyo boxes, I eventually decided to give this model a try. The price was higher than I was initially planning to spend, but the ability to have four heights made it more cost effective than potentially buying four fixed height boxes. I also considered building my own plyo box or using a 4-in-1 kit box sold on here. My concern with the wooden box was the stability on the higher heights. When the Stamina box arrived, I was surprised at how sturdy and stable it is. Plenty of room on the top platform and solidly built. My son told me that this is nicer than the fixed height boxes they use in the high school weight room. The height adjustment took a bit to get used to, but once I found the leverage point it's pretty easy. Overall I'm very pleased with this purchase and would recommend this to other family or friends.
