        Just the job!

        Arrived very quickly. Did not work on first attempt but left it overnight and it worked perfectly first time. Very pleased with purchase.

        Great Product

        As a novice I was a bit worried about how to recover my old system as it would not build properly but after a couple of questions I went ahead and ordered the USB version of Big Sir. When it arrived there were simple basic to use instructions on the packet and when followed the process was easy. I can highly recommend SRW and will use again.

        Customer service

        SRW was recommended to me and on viewing their site, found the Mac OS X 11.1 Bug Sur recovery/repair/reinstall USB. I wanted an easy-to-reinstall back-up system without having to delve into the Terminal, so ordered the USB. I later had another look through the site and saw a SSD pre-loaded with Windows 7. I emailed SRW with the specs of my old home build to ensure the hardware would cope with the SSD and got a quick, pleasant reply to the affirmative. Therefore, I ordered both. Despite being ordered on different days, both items arrived together, the next day.
        Very impressed and happy with SRW's service, competence and helpfullness.

        Easy Install

        The website was very intuitive and easily navigated. Products are fully described, including how to use them.
        Delivery was fast and the price very competitive. I have already passed the details on to a friend who has purchased and received his goods.
        I shall undoubtedly use this company again.
