What a pity more companies aren't this nice to deal with.
Review by confirmed purchaser
I had been told my computer memory couldn't be upgraded, but fortunately I emailed Mr. Memory before rushing out to to buy a new one. An immediate response from them assured me that I COULD upgrade and told me exactly what I needed in order to do so. The upgrade arrived within 36 hours and was as easy to install as I had been told. £40 instead if £400 - how great is that. This is a BRILLIANT company to deal with - they do everything they promise.
