Great!

I was looking to start to set up a home gym for my fiance and realize weights so are so expensive. This set didn't have any reviews, but I took the chance anyway and it's great! Right now we have it configured to two 22lb dumbbells and a 16lb kettlebell, but I'm thinking about buying one more set to make it more versatile. Highly recommend!

Great Product at a Great Price!

Great product at a great price. I was a little leery at first because of the low price. But I decided to take a chance and I couldn't be more pleased. All pieces are made of quality materials, tough rubber/plastics that handle the weights perfectly. I have a conventional (several times more expensive) all steel weight set and purchased this for use at another location and didn't want to spend a lot. After using it now for a couple of weeks, I cannot really tell the difference!! I would definitely recommend this set for anyone wanting some good weight training.
