It weighs a lot more than a single hammock stand; extra bulk.
It isn't capable of being used with a long Claytor JH.
Every time the person in the other hammock moves, it shakes your hammock.
It is too narrow.
Extra cost was about $110.

The single-stand is good though.

For campgrounds I am starting to lean more towards the imrisk single 2x4 solution, and the 2x4 cross member stand shown on in my photos on my site.

The 2x4 stands are much less expensive, weigh less, take up less room in the car and are very effective.

I am about to try the imrisk single board solution with the stake setup I use for the cross-member stand (shown in my photos).
