I think you will like it especially considering the cost. Be sure to go to Wal-Mart and buy a $3 space blanket and place it over the HH pad. Better yet, get a Heat Sheet:
Be sure and make sure the pad's elastic loop is lined up perfectly with the left side hammock tie out and the under covers exit hole. I have found I am better off not connecting the right side knee level pad loop. For some bizarre reason, it is about a foot too far towards the hammock foot end. If connected to the right side tie outs as directed, excess tension pulls it towards the head end and causes the pad to buckle under my knee/calf are. It did not feel cold, but that gap can not be optimum. It works much better left unattached on the right side, it smoothly molds under my leg. Even better: I ran a piece of cord from the pad tie out loop up the a screw link(mini-biner) on my ridgeline. Perfect! That snugs it right up to and molds it to my entire right leg.
