Primary Arms Deluxe Scope Mount Quality?

[DesmoDucRob]

I've been comparing a few one-piece mounts: Burris P.E.P.R., RRA, Armalite, Larue SPR, and the Primary Arms. I like that it doesn't have the unnecessary top-mounted rails like the Burris. The primary arms has exactly the features I want, and as a bonus, looks great, and is a few buck cheaper than the Burris. They appear to be popular, but I can't find too many details about how they hold up.

If I don't hear any positive feedback, I'll probably just go with the P.E.P.R. since I know they're well-made and relatively inexpensive, but I'd be happy to know that the Primary was equally well-made.

The mount in question:
