JFITPlyometric Boxes - Made in Taiwan NO Assembly Required Single - Height Box Set and Adjustable Box Options Plyometric Platform and Jumping Agility Box for Training Conditioning Strength Training

Its not heavy enough for plyometric jumps and will tip over.Ok for dumbells squats at slow pace.Any fast motions will make it tip over

Does what’s supposed to doI like it

The top is a rubber sheet. Slight peel, couldnt glue it down. Tallest needs to be weigh down even for light people. Other than cosmetic it will take regular abuse.

Im so happy with my purchase. They look and feel pretty sturdy! Did a couple box jumps to test them out. Totally recommend the only bad part is that they are stackable in order to use the smaller sizes you have to pick up the ones you don’t want to use because you cant just pull it out. They’re non slip and very well packaged

I bought these for sprint training, well made and stable. Strongly constructed.The black non-slip covering seems to have some movement as if its not glued only stretched around the base, but Ive had zero problems so far.If it rips or frays Ill fix it because everything else is perfect and the price is very low for 4 boxes that stack.

I love the box but it is a hassle making sure the rubber feet stay on. Sometimes the screws don’t always hold the pins still when adjusting the height

Received this product earlier than expected, kudos to that. Sturdy, does it's job. Got the adjustable height 18, 24, and 30 in. Got it on Fri 12/10/21. Using it for box squats, box jumps, and box step ups. So far been using the standard 18 in. height out of the box. Best tool for practicing box goblet squats, or any clean or overhead exercises to practice using core muscles and developing core strength. Haven't tested the adjustable heights yet, but for now it does its job. I like the width of the step up. I believe it's 16x16in. so enough space for box jumping and step ups. I shall probably do a post review later once a play with the adjustable height. Other than that it serves it's purpose. Hopefully this review will help customers on their purchase. I'll make it easier, as senator Palpatine says,"dew it!" Lol

We bought these in 2018 for our autistic son to have things to jump on and from other than our furniture. He graciously accepted our offering and proceeded to include the boxes in his living room parkour. We are on our second sofa and one of our chairs is pretty beaten up, but these boxes are fine.He is not jumping onto them from the floor, but he pushes them around into different configurations and jumps from one to another, or back and forth from them to furniture. My other kids have jumped around on them, although not nearly as much as he has. They also have been stand-ins for a step stool for me when I want to reach something up higher than I can reach.Now he has only been 40 - 55 pounds during the time we've had them, and my other kids are all 110 pounds or less, but I've been over 200 pounds this entire time and they have held up to all the abuse we've heaped on them. They were definitely worth the $200 we spent on them, but I'm not sure if I'd replace them for $300 if something happened to them. They do take up a bit of space, especially if they are not nested.

Returning as it arrived damaged. I don’t think it’s safe for exercise use anymore. Not sure how that corner is so bent because the box looks very sturdy, the packaging that it arrived in wasn’t damaged. Maybe it was like that from factory.Also £120 for delivery is a scam! I didn’t realise until I received it.

Missing rubber foot for one of the legs. Not in the box. So now it wobbles on the floor as soon as you stand on it.

Muy buena calidad y buen tamaño para lo que yo buscaba.Esta excelente para hacer ejercicios de pierna porque esta un poco mas elevado que un step normal pero no tan elevado que haga muy difíciles los ejercicios.Ocupa poco espacio en casa y es una buena pieza de mi equipo de gym en casa.

Everything I wanted and it came assembled.

High quality sturdy product with fast delivery. I have used the product numerous times and like the solid metal frame and rubberized top. It does not move when I use it for belt squats and I have loaded if up with heavy weight and it just feels solid.
