Benefits are probably quite limited. It allows you to camp where ground conditions do not suit - e.g. very wet, rough or not level ground, in dense or fragile (that you care about) undergrowth. Leaves a smaller trace of an overnight stop - lower impact of camp - good for military use or those who care about such things. Protection of sometimes poisonous things that bite in the night are all things that come to mind - while maintaining the group structure (unlike hammocks which are solo). Its current weight would prevent it being used for most of these situations.
Looks like fun and interesting and the benefits are probably not the reason you would buy or use one. I have not tried the product and don't particularly subscribe to the philosophy eluded to by the manufacturer, but should the opportunity present itself I am certainly a starter for a difference experience. I suspect it will be around for a while, but will always be a niche product.
