How well do Tikka factory mags hold up over the long haul?

Given the rather obscene cost of replacing them right now (in CAD particularly i bet), and not having been a Tikka owner longer than a year or two, been wondering about that. Ever break one or have any fails? Rough em up good and well, and have them survive?

Interested in long term and/or hard use stories, please!
