W.O. Bahtinov mask

The Bahtinov mask arrived on time and well packed with just the right amount of protection.
Rather expensive but it is a branded mask so thatís what you pay for
I contacted the help desk regarding wether I had ordered the incorrect side but the reply was prompt and I was assured that even if the item was opened the 30 day money back guarantee would still be in place so top marks for putting my mind at rest would highly recommend F.L.O. to one and all.

Very nice, very expensive piece of plastic

Wanted a mask that lets more light in. It's been said already that this is a very nicely made but very expensive bit of plastic. But I knew that and I am not disappointed!

Good Quality Mask. Much improved focusing through more light getting in. Should have bought one of these a while ago. More expensive, but thicker, stronger and better quality all round. It is what you need.

WO Bhatinov Mask

Quite pleased with the mask. It definitely gives a nice, clear diffraction pattern that enables quick, and precise focussing. The silicon-sleeved, adjustable screws grip the lens, or scope very nicely, with no danger of slipping if adjusted correctly. The mask arrived very well packaged, and seems to be a very nice piece of kit. I canít give it five stars though, as it is incredibly expensive for a sliver of PVC, no matter what grade of PVC it is.
