Of course what this double cymbal stands provides, you can do with a regular stand and an extra expansion arm.
However, I really liked the fact that this is a dedicated double cymbal stands, where both cymbal arms are the same distance from the center of the stand.
I put my 22" ride and 18" crash, and have no problems.
It doesn't look extra heavy, but it is very solid, and it doesn't give way to the weight.
Pros:
Great quality
Very stable
Great dedicated double cymbal desing
Cons:
None
