I don't like leaving bad reviews, but I think I have to for this site. Bought ram from them that they stated on their website was compatible with my laptop. Installed it, it turned out not to be compatible. Messaged their support, they tried to be helpful but after I'd spoken to Crucial support (the brand of ram they'd sent me), they explained that MemoryCow sent me one that wasn't compatible, and I should instead buy one with a different model number. Told support, they came back with false information about that, even though crucial had told me the opposite. Ended up buying straight from Crucial because it was £10 cheaper, it works fine. In returning my product to MemoryCow, it took a week and a half for them to receive it back. A further week and a half for them to "process" my return. And now a week for my paypal refund to go through. A month for a £43 refund is a joke.
