Please don't purchase this nailer and expect to use it for contractor use. It just isn't that type of nail gun. Slow and methodical is the name of the game with this one. You are not going to be firing nails as fast as you can pull the trigger. It will countersink 2 inch nails through 3/4 oak plywood and into a 2x4. However, there is a delay when you pull the trigger and if you pull the gun away from your workpiece to soon, it will leave the nail proud of the surface. Also, if you don't hold it firmly enough against your work piece then the resulting kickback will leave the nail slightly proud of the surface. If you exercise proper technique and patience then this gun will meet the homeowner/hobbiest use. I use it to reinforce glue joints on some of my projects. I also use this every weekend as woodworking is a hobby of mine. I thought about getting the dewalt nailer but it is a lot more bulky than the B&D and I felt that some of my projects require something that can get into smaller spots. Something you might consider depending on what your application needs are. Also, the cost was 1/3 of the Dewalt and at least half of any other 18 guage cordless nailer I could find at the time. So after reading some reviews on this one I purchased two of them for a couple reasons. First, I like to use differnt size nails on the same project and this would allow me to not have to constantly change out nail sizes. Second, based on some of the reviews I read I felt that if one broke down I would still have one that worked while I sent it in for service. Which brings me to the 2 year warranty that comes standard with this model. 2 months and about 200 nails into it, one of the nailers stopped working. The indicator light was indicating low battery and wouldn't fire. It would do that with all six of my batteries as I have other 18v B&D products. I took it to a local authorized repair center and he said B&D would probably just send me a new one in the mail. No hassles. So in conclusion I would say that this is a decent product that might give you some mechanical problems but the 2 yr manufacturers warranty makes it worth it.
***Update***
July 16, 2010. B&D has had my nailer since 6/21/10 for warranty service. Found out today that they will not be replacing it or repairing it, they will be sending me a check for the purchase price including tax. I asked how they would know how much I paid for it and the rep said they use a regional sales figure that is the same for all authorized retailers. I'll update this review when I get that check.

July 26, 2010. Recieved the check from B&D today. I was concerned about the amount I would get but, that concern was unwarranted. The amount covered my cost completely. After this, I am more than willing to add more B&D tools to my collection.
