I only hear good things about them on other forums, mostly from people on a Leica forum. I purchased covering for my Minolta Autocord TLR and it fit perfectly and looks good. The only negative is you have to keep after Morgan for delivery. He gets busy and a little bit of the "squeaky wheel" theory applies. But from posts of dozens of people I've never heard a bad word.
The hardest part of the process is usually completely taking the old covering off not putting the new on.
