My husband has been looking for a set-up like this for a long time. We were initially going to go with Bowflex, but he was introduced to PowerBlock by a friend. After doing tons of research, we found that PowerBlock had a better warranty, and was made from more durable materials (no breakable plastic pieces). Ultimately, we decided on PowerBlock. He has been using the dumbells for a few weeks now and absolutely loves them. They are comfortable to use, and so easy to adjust. PowerBlock is definitely worth the price, and it is wonderful not to have tons of different dumbells around of varying weights. A great space saver!!!
