I've not actually used this yet, but I did get it out of it's bag to take a look. As soon as I removed it, it unfurled itself in a somewhat explosive fashion sending a glass of wine flying, and giving me a black eye (really!)
I can't work out now how to get it to fold back up again. I can get it to twist into a kind of figure-8 but it doesn't seem to want to fold over then. There aren't any instructions with it, and I think this is a big oversight.
Other than that, the material looks a nice clean white and with plenty of lighting I'm hoping it should give good results.
