Pros: ease of adjustment, easy to store (without stand), good weight range for any workout.
Cons: cost if you buy at full price, a bit bulky at first.
I'm a recent buyer, but I'm already thrilled with this product. I've been working out for 22 years now, and these are a fantasic workout tool. I recently started the P90X program, and the dumbells are perfect for that and other workout programs. I managed to get a great sales price from Sears through Bizrate.com so I paid just $299 for my set. I wouldn't have wanted to pay the normal price, but at this price I'm VERY pleased with them. The adjustments are SO SIMPLE and even though they are a bit bulky at first you get used to them quickly. You won't be disappointed with these.
