I bought this item to help me improve my stamina for jiu jitsu gradings. It's made well, although the vest is largely made of one type of thin material, so it's quite hard to lift when you've got all the weights in it. The straps are inadequate for holding the fully weighted vest in place if you do any kind of exercise that requires a lot of movement. Even jogging can be difficult in it as the entire vest bobs up and down as you run, and the straps then work themselves loose.
Having said that, this vest is a lot cheaper than the other models and this is probably why. It does at the end of the day allow you to strap a load of weight to your body! You may just need to add a couple of extra belts or straps in order to properly secure it if you use the full weight. I'd still recommend it if you want a weight vest on a budget, but just factor in buying an additional velcro strap or something similar.
