We use the 552's for general fitness and of course, weight control/loss. They take up minimal space in the workout area and as far as I'm concerned don't have any downside.
I use the 552's to do a light workout 4-5 days a week.very easy to change weight.targets muscles very nicely. DVD that comes with them is very helpful,the four step rep is awesome.
Pros: Compact, Durable, Easy To Use, Multifunctional, Targets Muscles
The set is compact in the sense that it doesn't take up much space as far as a full set to fifty each. The dumbbells themselves however are very long no matter what weight you are using.

This product should be reduced in length. It is too bulky, especially for women. It would be more convenient if this product was scaled a bit more, rather than attempting to get everything in on or two devices. I could see a set of two for the same weight range. Even though this product has the total range of weight, it still doesn't make me want to get rid of my other dumbells as they are better for some exercises.
