I've had a Rami (bought used) for about 2 years now. I've never had any trouble with it, but it's starting to be more sensitive to lubrication. The return seems a bit sluggish unless it's very well oiled.
As I've put about 800 through it, and I don't know how many were through it before I got it, I'll change out the outer recoil spring and see how it goes. Other than that it's accurate, easy to shoot well, and trouble free.
I don't carry it, as my hands don't seem to find the mag release easily, and when I do, the mags catch on the heel of my right hand, making it necessary to pull them out during a reload.
If my hands fit it better, I wouldn't hesitate to carry it.
