Installed on Macbook Pro (5,3). Had to research beforehand what was needed and reviews so decided this was the best value for money at the moment.
I was tempted to go for the 840 Pro but the extra cost was not worth it.
Very happy with the SSD so far. Hugh improvement in speeds, both start-up/shut-down as opening apps.
Please remember, if upgrading your Macbook Pro, to enable trim. I found Chameleon SSD Optimiser to be very useful enabling Trim and a few other tweaks.
