I bought an iLap the same day I purchased my MBP because I had heard people say it gets really warm under load. Yesterday was the first time I had a chance to put a load on the MPB when it was adding all 7000+ of my iTunes songs. The iLap performed as promised it took the heat from the MBP and spread it out over the metal surface all the while I had no idea the thing was even hot until I touched the iLap. They are most deff worth the $50 bucks! Highly Highly Recommended.
