I took my girlfriends Macbook here to upgrade the RAM. I called around to some local shops and found most places didn’t carry the RAM or it was pretty expensive. Tom assisted me in looking for the correct RAM and quickly and easily found it. I also got a great deal. I’ll be taking my computer here again. *EDIT* Unfortunately I had to take a couple stars because the RAM went bad after about 6 months. I honestly wouldn’t be surprised if he gave me a refund but at this point it’s not worth the hassle. It would’ve been nice if this hadn’t happened. I think it’s because the RAM he sold me was second hand, so you get what you pay for. I’d still take my computer to him but I’d be more cautious about buying second hand parts.
