Some people are still having problems with the newest 1.37 adapter. I love the Novo 4. Just understand it is not as simple as using a Xulin. A couple if my friends got tired of having to mess with the Novo 4 slipping occasionally and switched to the Xulin.
I don’t mind messing with jt, so I still use the Novo 4. But it is definitely not always going to work…
