STAY WAY FROM THIS COMPANY!!! I ordered several memory sticks from Rambusters and over half of it was faulty and didnt work at all. I asked for some replacements and did not receive a reply. I kept emailing, phoning and after 3 weeks eventually got hold of them (I phoned from a different number) and they said it had been posted out and to wait another week! So I waited another a week - still no replacements, they kept stalling me by saying to wait, but after 8 weeks of waiting and exceptionally poor communication I just gave up! They even told me I installed it wrong and to watch a YouTubve installation video - If I had installed it wrong how come some of it worked and some didnt?? Just yet another stall on their part. If you order anything from these cowboys make sure you do it via PayPal so you can get your money back - In good faith, I made the mistake of wire transfer to save fees for both parties but this is the risk you run. They probably wanted a wire transfer so they dont have to worry about giving refunds! WORST CUSTOMER SERVICE EVER!! - BLATANT THIEVES!!
