Bought this screw gun to screw down subflooring on a house addition. Thought it would make a multiple day job on my knees , a one day job standing up. When it worked, the screw gun was great. Drove most screws flush. But it would soon start to strip screws and not drive them all the way in. I figured out that the bits were getting worn fast. As soon at the bit became worn, it wouldn't drive the screws all the way. Each box of screws comes with 2 bits, but that's not enough to even drive half a box - and the bits are small (special) not the standard 1/4 inch hex bits and hard to change out. I would recommend buying a couple of packs of bits for each box of screws you buy. I've got a drywall job coming up and I'll give it another chance, but right now I really wish I hadn't purchased this tool.

Bad Points:
br /-----------
br /
br /- My 1st QuikDrive unit did not work out-of-the-box, had multiple problems with the driving unit including screw strips that jammed, and a depth adjustment that would not rotate properly
br /
br /- Driving Unit on the QD 2000 is a cheaper form of the one available on their pro unit
br /
br /- Screw Strips come in lengths of only 30, requiring frequent changes [you'll need several just to get through a single sheet of plywood]
br /
br /- It is difficult to find local retailers that carry the screw strips. Home Depot, [most] Lowe's, and Sears do not carry them
br /
br /- DeWalt drill that comes with the kit is known to have a weak clutch that wears out sooner than their Pro models which use a Makita drill
br /
br /- Instructions are too brief, do not provide a parts list or inventory, and include assembly instructions but not actually *operating* instructions
br /
br /- Bits not always easy to remove, and are non-standard (you can't use the regular bits that are available for drills, you must use a QuikDrive bit)
br /
br /
br /Good Points:
br /------------
br /
br /- When it works it saves you a ton of time and energy, and is consistent with the depth it drives screws
br /
br /- QuikDrive customer service is excellent
br /
br /- Comes with two nozzles so that you can drive screws up to 3" in length

First off, the screw bits will round off if you keep screwing the floor when the screw is already sunk. So, DON'T DO THAT. It takes a little practice, but not more than a few minutes or so. I am a builder and screw down the sub-floors in my houses myself. This tool makes it very efficient, although I do wish the strips contained more than 30 screws in each. It hardly ever misfires, but if it does, I just get rid of the messed up screw and move on. About getting the bits out, it comes with a freaking tool to pop them out. It doesn't take much to get them out if you use the tool. Slide the hook through the slit that is under the inserted bit, and then rotate the tool 45 degrees or so and the bit pops out. For extra bits, just search the internet for bps-3 and quikdrive and you will find them. I did one sub-floor with a normal screw gun and even with knee pads it sucked. This tool is awesome and allows me to screw down the sub-floor in a 2000 square foot house in just a few hours.

This is a great labor saving tool that I have used extensively. The Quik Drive works great if you just play by the same rules you would use with any screw gun. DON'T LET THE BIT GRIND! Quik Drive includes 2 free bits in every box of screws and this is more than enough if you don't let the bit spin and round off in the screw head. I can typically get through several boxes of screws on one bit. Stay on it and follow through, remember this is a screw gun and not a nail gun. If you start having trouble, check the bit and replace it if it is rounded. Do this and with a little practice, you can save 50-80% of your labor. This is one of the best tools I have ever used!

This screw gun works fine, but there are much better products out there for the same price. All of the Superdrive products I have used work better than this gun, and the screws are more available. We have two of these guns and both of them have jambing issues, driving flush issues and little levers and adjusters breaking issues. Try the Pam system, superdrive or Hilti Superdrive...
