Very easy, affordable and quick plate. Have they built into my MacBook Pro Early 2011. Bought This Item Also I have a 8GB USB stick and also available here Hama Screwdriver Set for installation (approx. 12 Euro). First, I installed Mavericks with DiscMaker X on the USB stick. Then secured with Time Machine, a complete backup of my data to an external hard drive. Hard disk with the Hama Screwdriver Set expanded. Thus, the SSD has the right height, a stick-on plastic plate is not included. These glued, screwed everything. Finished after 10 minutes. Mac while holding down the "ALT" started, starts the Disk Utility. The SSD was immediately recognized. SSD formatted USB Stick plugged and installed Mavericks. The installation will take 1 second approx remained hanging for 20 minutes not let them confuse. Just wait! After successful installation of Mavericks via Time Machine partly filled with the old data, done. The MacBook runs and one hears only a very very small voice of the fan. Absolute buy recommendation!
