Hi rob1261,
I think the Luna is one of the better choices of the thin membrane type and is one of the more popular options mentioned in the mattress protector post.
There are a number of people on the forum who have purchased the same one you have and seem quite happy with it and the only negative comments I’ve heard is that for a few people it can sleep a little warm but that’s common to most of the membrane type of protectors. It should work well for you and it’s good value compared to some of the others as well.
