"Ordered memory upgrade for my HP Omen 17 laptop. Arrived promptly, one stick proved defective after efficient troubleshooting via their chat. Advance-replaced the bad stick very promptly, it also proved bad. I decided to re-upgrade, which was promptly shipped with a prepaid return label for the bad stick. Refund issued with amazing promptness. These are the people you want in your corner if you run into problems. No BS, just fast solutions."
