    Flexx are recomendded by EveryMac. I normally purchase RAM from another supplier but the data on their site left me concerned that the item wouldn't work in the iMac it was intended for, additionally their pricing was steep. The product was purchased to upgrade a "Vintage" iMac to an unsupported config. Accuracy was essential and the item worked fine. Service and delivery are also above expectation.

    I ordered the 4GB memory RAM and received in few days. It was to upgrade my MacBook Pro early 2008. I easily installed and it works perfectly with 6 GB total.
