I bought this because I needed one of the bits to replace my battery on my Macbook Pro 13" Mid-2009.
Repair was smooth and easy.
I was pleasantly surprised with the quality of this set. It's unlike any other bit set i've seen.
The bit "cartages" come out so you don't need to wrestle with them to get out a bit. The screwdriver itself is high quality and smooth to operate.
Overall I found this to be a great purchase.
Also, It shipped and arrived (internationally!) in just over a week probably fastest delivery i've ever gotten.
