Well made simple product
I just received this mask in the mail a couple of hours back because I wanted to purchase something more durable than my home made Bhatinov mask. If you have never used one, the mask comes with clear instructions on how to use it and the instructions are in color which is a nice touch compared to some cheap photocopies I had seen with some other products. My only complaint is that there is a lot of fine black powder from the machining and as soon as I opened the pack I had black stains on my clothes from this powder. Now imagine that falling on your optics. The products should have been thoroughly washed by the manufacturer after fabrication but before packaging.
