Just to say well done. Ordered 2 x 2GB RAM for my ageing Acer Aspire 5633WLMi laptop (to upgrade from its original 1GB in total!). Looked (well asked my husband to look) at 'how to' video on Mr Memory website, h did dummy run, then actual replacement, and, hey presto, it all worked. Start up (and shut down) time has now dramatically improved. And forgot to say that also give full stars for delivery - ordered on a Sunday night, RAM arrived Tuesday. Well done all round.
