I got my Jarbidge in the last sale and IMO it is worth every penny of the full price!
I use mine with a "triangle thingy" on the foot end and the stock suspension on the head end with removable quilt hooks. Works amazingly well. I was using the triangle thingy on the head end, but the mini carabiner was hitting my head.

I've used it down to 33 degrees and I was toasty warm. It is rated to 25 - and I have no doubt it would still be toasty warm at that temp. ImageUploadedByTapatalk1413770495.626350.jpg
Here it is on my 11' Dutch Argon hammock.
