"Khyber Pass" 40 Round AK-47 Waffle Magazine

I purchased one of the recently imported "Khyber Pass" AK magazines from Pakistan for my collection. I chose a 40 round waffle magazine - made of steel. There were never any original 40 round waffle magazines and they were only 30 rounds. I compare the magazine side-by-side with an original aluminum waffle magazine, also known as paratrooper magazines, showing the differences in weight and construction.Does it work and feed well?
