This. You have full manufacturers warranty so isnt an issue.
Ive had some crackers. One was perfect but missing the remote but not a big deal and another B grade forum buyer posted me his. Think it was £200 vs the £350 they were new in the shop.
Last one was the current Benq 32" 4k. perfect, nothing missing and £250 off the price in the shop.
BTW if you dont think the B grade price is low enough vs new then send ocuk a webnote.
I think they had my Benq at only £70 off as it had come down in price from what is was originally. One quick webnote later and the guy at ocuk had dropped it another £180.
Rough rule of them with monitors is that you shouldnt be paying more than two thirds the price of the current new price.
In fact just realised that apart from the brand new monitor I bought at two thirds price on ocuk shop opening day, all my monitors for the alst ten years have been B grade ones.
And if you swap often you quite often get most of your money back when you come to sell them.
