It has been used a few times and held up very well with no tip distortion.
The last use was for a Macbook Pro SSD upgrade that was completed successfully with the help of this product, but please note that to actually gain access to the inside of the Macbook Pro, you'll need these: LINDY Computer Technician Precision Screwdriver Set, and then the Torx set to actually remove the HDD/SSD.
The screwdriver set came well-packaged, it also included a nice plastic case where each screwdriver stays put until you need it.
For an affordable price, you can't go wrong. This included Torx T6, T7, T8, T9 and T10 with 20mm-long bits.
I recommend this product based on its quality and price.
It's worth noting that this is NOT Torx Security (with a hole in the middle of the bit), this is Torx only, therefore it won't go inside Torx Security screws (that have a pin in the middle where the hole in the bit slots in), as an example the XBOX 360 controllers use Torx Security screws therefore this set won't work if you want to use it to open the XBOX 360 controller.
