No problems in about 13 years !
I've been shopping with Overclockers UK since about 1999 and have ordered via post and in person. Can't even imagine how many orders I've made over the years, customer service is great. Personally I am glad that OCUK handle RMA issues, otherwise if you buy from elsewhere you could find yourself paying the postage to RMA components to anywhere in Europe (Corsair for example have their RMA base in the Netherlands). I guess there are always going to be people who just cannot be pleased ! I would highly recommend OCUK so thanks guys for the great service !
