Got two of these to play with the new time crysis, good looking guns, but the build quality does imply you get what you pay for. My friend has the official sony guns and although they dont look as sexy, their build quality is far more superior and is much more comfortable in your hand and is much better to hold overall.
These guns to what they say on the tin, so if you want a cheap solution then go for these. My only concern is due to the way they are constructed I dont think theyre life span will be that long if playing games like time crysis, i playd for a couple of hours and the trigger straight away got louder (spring) and harder feeling.
I think i will be replacing them with the Sony guns in the future, but these will do for now.
