So far so good, but when used on the taller sides, I realized that the foam block inside is not one solid piece. There are two separate pieces of foam stacked on top of each other and they don't seem to be glued together, so they sometimes compress or shift unevenly. This makes it a bit unstable if you land with too much forward momentum. When used on the shortest side (as in the product picture with "Sunny" facing you, written horizontally across the front of the box, the top piece of foam will sometimes shift/slide a few inches forward while the bottom stays in place. This causes the box to tip forward. When the box is flipped on its side for a higher jump, if you land toward the front half of the box, the piece of foam on that side compresses more than the foam on the near side, which causes the box to tip. I've had to bail out and quickly jump off the front of the box a couple of times, so I definitely suggest gibing yourself plenty of space around the box when you use it.
**Also - if you want, you can think of this as a feature. It has really caused me to concentrate on jumping with more force up than forward so that most of my momentum is coming straight down when I land. It makes me really focus on sticking the landing and using my muscles to balance as soon as my feet hit the box. Again - just make sure you have space around you in case you need to bail out and quickly jump to the floor. And try not to use it on concrete in case you need to fall completely.
For the price though (compared to other boxes), it's definitely still a great deal, so it gets 4 stars.
