Customer Reviews
I purchased an SSD hard drive pack. I found getting the screen off the Mac and changing the hard drive easy but, cloning the hard drive I found a little bit more challenging As I have no tech skills whatsoever. Flexx was there to help me via email and was really happy with there quick response even over the weekend.
Thanks Flexx!
Would 100% recommend.
If you follow video the instructions, adhesive 4R will cover iMac microphone resulting into a wrong display sealing. After you turn you iMac you will find that microphone do not work properly and sound level very very low.
This kit has totally transformed my wife’s IMac. It’s made improvement s in all areas, boot, running heavy programs like Adobe Cc, and just general speed.
The kit provided everything I needed, and luckily had a duplicate set of double sided edge stickers, I needed them..
