Bowflex makes a solid product. These are all you need if you are looking for a set of dumbbells. Selecting your size is easy, the grips are comfortable, and they don't take up a lot of space. That said, they are a bit cumbersome at first because they are a little bit longer and wider than standard dumbbells. You need to be gentle when cradling them, as well, because if they are dropped into the cradle the plates will start to stick, and eventually they won't work anymore. This is my second set because the person I was sharing them with did exactly what I just warned against. Needless to say, no one uses this set now except me. Used properly, they will last a long time.
