Most common complaint seems to be that it only holds 3 down in the magazine. Very smooth bolt right out of the box, mine was very accurate, as was the 416 rem mag version I got a few months later. Another complaint by some might be that other than the venerable 375 H&H... It comes in 416 rem mag, not 416 Rigby, and 458 Win Mag, not the Lott version. But in 375, it is superb! And nothing wrong with a 416 Rem Mag!
They come with the trigger a bit heavy for a hunting rifle and I shoot mine more accurately now that I've turned it down to 3 pounds, which is as low as it goes (by backing out the screw all the way). You need to add scope bases such as weaver mounts where a CZ or Ruger have integral bases machined in... But on the other hand this lets you use any rings you like. Only one rear sight, no flip up... but hey, it is an economically priced gun that is inherently, accurate, comes with a barrel band swivel, express sights, CRF, and works right out of the box!
