Tikka Ringmounts; durability?

I was wondering if anybody has anything negative to say about the Tikka Ringmounts? The one piece ones.

Have they stood the test of time on your rifle?

The rings are ok, the screws can be a bit shit

You can get replacement screws I think

The big drawback is they come free with the rifle and just work.

Using the standard ones on my 300wm and had no issues apart from them being a bit ugly.
