I got the Mach 3 Turbo + screwdriver combo at the Harrisburg, PA. Target store. Decent screwdriver for a promo item. It has a little rubber collar around the base of the blade that holds 5 or 6 interchangeable bits. Looks nice, has a stylish, rubberized handgrip, but this is not a ratchet-type mechanical screwdriver. Good for keeping in the kitchen "junk drawer" when you need a versatile screwdriver quickly and you don't want to go digging your cordless screwdriver out of the toolbox. Within a week, my nine-year-old son took a liking to this screwdriver. It hasn't been seen since. Sigh. At least the price was right...
I believe the Mach 3 Turbo blade has two lubricating strips, one above and below the blades. I think they skipped the little rubber fins in favor of the second lubricating strip. I found the shave to be about 10% more comfortable than the regular Mach 3, and for what it's worth, I got five shaves each out of the two cartridges that came in the promo pack, instead of my usual 4 shaves with the regular Mach 3 blades.
