Bests & Worsts Reviews from Amazon

I've used the old-style Pro Tech Toolkit for years iFixit Pro Tech Toolkit and it's never let me down. I recently upgraded to the new 2016 Pro Tech during a black friday sale and have had some time to use it. The new 64 bit kit iFixit 64 Bit Driver Kit is the star of this toolkit by far, but I was very impressed with all the components. See my video review for details on some of the changes and upgrades. Update, things I've discovered since making my video review: The steel used for the bits is 6150 (manufacturer's website), so it contains 0.5% C, 0.8% Mn, 0.9% Cr, 0.18% V making it a type of CR-V steel, commonly used for knives and swords. "6150 is a fine grained, highly abrasion resistant carbon-chromium alloy steel. Very good shock resistance and toughness are also key properties of this alloy in the heat treated condition." I'm still amazed at the machining quality of the bits. Here is a list of applications I'm aware of for some of the special bits you won't find in other kits: 5.5mm Nut Driver - Printer and copier repair Spanner/Snake-eye bits - Security panels, elevators, bathroom hardware. Square/Robertson bits - Common in Canada/Australia JIS /Japanese Industrial Standard - Used in cameras, remote control helicopters, drones and other electronics. Torx Security. TR6 - Apple Mac Mini TR8 - Xbox and some HP printers, other assorted electronics TR10 - Playstation and HP/Compaq computers T15 - HP/Compaq/Lenovo hardware Gamebits 4.5 and 3.8 - Nintendo and Sega consoles/games Y000 - Apple Watch Y00 - Apple track pads P2 - iPhone bottom screws P5 - MacBook cases P6 - MacBook Batteries
