Review on Original Release Handle Instant ZoneFly by Abdulkarim Sugge

According to the description on the website this is to be a replacement exhaust valve for my original DUO SV 60 model but when I receive it the exhaust valve is smaller than the original. My original valve also uses a different steel cocking mechanism. I don't mind using a plastic ring as a replacement as it can be more durable than the original. This clip fell out a few months after I received this record, although luckily I found it each time, this clip eventually broke at one end. This replacement valve gear looks better and won't fall out. However, the smaller interchangeable handle is not big enough for me to turn the handle and stay in the closed position. So I have to remember the position of his seal, otherwise I might pass that position. Not as good as the original, hence one star.
