I just bought 3 of these sheets, one each for my summer 30 deg F bag, my shoulder season 15 def F bag, and my winter 0 deg F bag. The summer bag has the green non-insulated sheet the other two have the insulated version.
I just recently found out about this sheet and my first response was "why would anyone need that". Then I started thinking about it. I have three Klymit Static V insulated pads. I keep one in each of my bag's storage sacks along with the sleeping bag, a Klymit Pillow-X Large, a Cocoon microfiber bag liner, and a compression sack for the bag. That way, I can just grab any given storage sack and go without worrying about rounding up all the pieces or worrying about forgetting something.
So the Static V pads are pretty good for comfort. And they aren't that noisy. Not enough to wake me up anyway unlike some other ultralight pads that sound like you're sleeping on a potato chip bag. But I have found a four things that either bug me or could use some enhancement.
1.) I use a Klymit Pillow-X Large the combination of the pillow and the Static V pad make keeping the pillow in place for more than 15 minutes almost impossible. So my solution and been to put the pillow inside the hood of my sleeping bag. That works but it's not ideal.
2.) The Static V pad and the nylon of my sleeping bag likewise make it hard to stay on the pad for a full night. I've had no solution for that up to this point.
3.) If it's warm out I sleep on the pad and leave the bag unzipped to use as a quilt. The pad doesn't feel bad but its air proof / waterproof nature means it can get sweaty / icky.
4.) The insulated Static V has an R rating of 4.4. That's generally a good 3 season option for me here in New England. But I thought the sheet would make a nice addition for winters and single digit temps by adding an R value of 2 for a total 6.4 rating.
So how does this insulated sheet work?
1.) It nails the pillow issue. The pillow will stay in place all night and it won't be inside my bag. Much more comfortable.
2.) It nails the slippery nylon / on nylon problem. There is plenty of friction to keep you on the pad.
3.) The sheet feels much better than nylon against your skin. It's like a microfiber bed sheet at home.
4.) The added R rating is an open question. I haven't had it out in single digit temps yet.
Downsides? I've found one. The sheet fits tight enough that it scrunches up the pad enough to lose about 3-4 inches of length. I'm exactly 6'0" tall so the pad ordinarily is just long enough for me. With the sheet on my feet hang off by about 4".
How hard is it to put the sheet on? Not bad at all. The fit is good if a little tight and the strap in the center seems to keep it in place well. The pad may pull up at first from the tight fit but lay on it for a couple of minutes and everything flattens out pretty well.
What about the weight? Klymit is ummm.....optimistic about the weight of their product. The stuff bag says 243 grams. I measured it with a scale accurate to 1 gram and what I found with both of my quilted sheets is that the sheet by itself weighs 296 grams while the sheet and stuff sack weigh 314 grams. That's a claimed 8.6 oz vs a measured 11.1 oz., about a 2.5 oz error or 29%. Not the end of the world but not honest either.

4.) A tape measure showing the loos of length from the sheet compressing the pad.
5.) The sheet on the pad with the Klymit Pillow-X Large inserted in the pillow pocket.

So is it worth the cost and the weight? To me, yes. The pillow pocket and the added friction are worth their weight in gold for keeping everything together all night and allowing me to sleep. An additional 11 oz doesn't seem bad if you can get a solid 6-8 hours of uninterrupted sleep. And the sheet + bag liner may allow you to ditch the sleeping bag in warm weather.
EDIT 12/22/2017: After playing around with this sheet as part of my sleep system for a while, I'd like to offer two suggestions for better comfort.
1.) A smaller pillow may be better than a larger one in this pillow pocket. I have the Pillow X Large. In the photos it was blown up all the way. That really filled the pillow pocket too much. The regular size Pillow X may be the better choice in this pillow pocket.
2.) Alternately, if you already own the Pillow X Large like me, I'd experiment with letting some air out until you find a compromise between fit in the pillow pocket and sleep comfort. Also having the pillow fully inflated exacerbates the problem with using the full length of the pad. A flatter pillow that fits in the pocket better will allow you to scoot up a couple more inches on the pad.
Hope this info helps you make a decision.
