Ditto, but I can say that at least when they went to the Sefar panels, they worked. The originals were funky and required much tweaking (double rolling a side sometimes, an end sometimes). Originally no consistency on sizing, the one thing that a panel like this really needs!
You may want to find my recent post and ensuing thread about the similar product from Dynamic. The frames seemed nicer, and then also, Shurloc has a similar product that seems a step up.
I'll try to find it.
