Thanks for the memory!

I bought a 2Gb memory chip to upgrade a Samsung Notebook which was grinding to a halt, using most of its existing memory just to keep XP running. Doubling the memory has made it usable again, when it was looking like it would soon only be of any use as a paperweight. The memory from Offtek was very reasonably priced - especially compared to the price of a replacement laptop - and they delivered it quickly and well-packaged.

Faultless Service!

I have had two transactions with Offtek....firstly I bought some PC memory on Ebay...they contacted me immediately telling me it wasn`t suitable for my model. They posted me the correct memory needed and refunded the difference(which I thought was pretty good of them as it was my fault!).Secondly I bought a flash Memory Stick which was sent by return.Will always look there first if similar goods are required.Good communication and fast service!
