"I have owned many multi bit screwdrivers over the years, and this one is simply unbeatable! You do not lose bits from this screwdriver like you do for other multibit screwdrivers. The bits are in the handle but you never touch them to change them so you can't lose them. To change a bit, you simply pull back the handle (it becomes twice it's normal length) which retracts the bit, you then rotate the handle pointer to indicate the shape of the new bit you want, and then when you collapse the handle back to original size the new bit is at the tip ready to use! This Mastercraft screwdriver is simply a rebranded Autoloader brand screwdriver, but the price on the Autoloader brand at other places are the same as this one here, so buy it from Canadian Tire as you get a much better warranty."
