My experience is limited to shooting only one sample, owned by a friend of mine. I'm sorry, I don't know the specific model. I think it was made in Russia.
The finish on his was not high quality with salt residue in places where barrels joined toghether. A thorough cleaning took care of that problem.
The gun was rough and very stiff to open and close, but keep in mind, it was brand new.
There were no malfunctions of any kind and everything operated as it should. My friend uses his regularly and nothing has broken.
Recoil seemed much more severe than on my Browning, and if you are going to shoot it all day, that could become a problem.
And far as value, I think it is exceptional. It does everything a shotgun is supposed to. You cannot expect to compare it with a $3,000 gun. Dollar for dollar, considering mechanical reliabilty, and if you are on a strict budget, I would recommend it.
The only real negative I had with it was the automatic safety. Many shotguns today have this feature which I find a MAJOR annoyance. This is not recommended, but he did have the automatic safety disabled. He can still use it manually.
