My Mrs picked one up last week but we won't be using it until next week. TBH, I was a bit sceptical about the thermal protection bit and only a little less sceptical about it's reputed ability to reduce condensation in the awning but we will see (it was only £20 so hardly a major outlay!). I'll report back after next week if your interested. That said, I think we will be lucky if the sun comes out and is strong enough for us to need the thermal bit.
