They are a good little rifle, albeit a bit quirky. Well made and tend to be very accurate. The .22 Hornet is a good little round for small game at ranges out to about 200 yards.
I have the predecessor, the Brno ZKW465. The Fox 2 is a revision of that rifle, which has a less "European" stock and was available in .222 as well as .22 Hornet. Some find the double set trigger hard to get used to, but I like it, and it soon becomes second nature to set the trigger as you get ready to shoot. Some complain that it is hard to mount scopes low too, because of the thickness of the root of the bolt handle, but I haven't found that to be an issue on my ZKW465 - maybe if you use a scope with a large-diameter eyepiece it would be, but you could always dress the bolt-handle down a bit I guess. The safety on mine works "back to front", as you pull it back to "fire", and IIRC the Fox 2 is the same, but it doesn't bother me at all.
