Rated 3.2 out of 5 by 94 reviewers.
Rated 5.0 out of 5.0 by Best thing since sliced bread I have a landscaping / construction business and this is one of the best tools I have purchased lately. I have built multiple large decks with my first collated screwdriver and I loved it so much I went out and purchased a second one for my employee or in case one where to fail. I have hung drywall by myself with this as well and it is excellent.. Learning curve is about one strip of screws. Found to help seat the screws better it is beneficial to have the drill spinning and use two hands to put screw into place with decking screws to keep from sliding off. Screws are expensive but what I save in time it is worth the extra money. I went from taking 6 hours to screw down a medium sized deck for 2 people to 45 minutes to an hour with this tool. Worth every penny!!! May 19, 2015

Rated 4.0 out of 5.0 by Don't know what some of you are having a problem with this tool is awesome if you know how to use it can not screw on a angle if you take the time to read the manual it will tell you you need to drive screws in straight not on a angle .also check to make sure it's on drive not reverse I have to put no pressure what so ever new material or old to drive screws in .yes you do have to adjust depth to reach desired counter sink I have use this tool for hanging sheet rock to laying subfloor with no issues and just a little fyi mark your studs or you'll be floating in the wind I have banged out rooms in half the time it would take to keep reaching for a screw I have owned this tool for well over a year and have not had to replace my bit yet maybe this tool is more for a professional than a do it yourself type of person ...and no I do not work for ridgid I'm just a typical contractor that has a arsenal of dewalt tools this ridgid just happened to have been add to my choice of weapons January 22, 2015
Rated 4.0 out of 5.0 by Good Gun, Definitely Has A Learning Curve Let me start by saying that this is NOT a good gun for weekend warrior / homeowner DIY'ers that want to hang a few pieces of drywall with as little hassle as possible. If that is what you are looking for, then just stick with a regular corded or cordless drill and drywall bits. This gun will not just magically sink every screw perfectly, it requires you to shoot at least a hundred screws to get the technique down, and it will require you to put your weight behind it to get screws to sink. I am a homeowner, and I bought this to finish my garage with 18 panels of 4'x12' 5/8" type X. I read the reviews on here, as well as on some online forum discussions about using auto-feed guns, so I was ready to accept that it would be difficult at first. I shot maybe 30 screws to get the depth set where I wanted it, and it took around 200 screws to get the feel for the technique. What is this technique? Well, as far as I can tell you need to do these things: 1) Push HARD on the gun or the bit will just jump out of the head and start stripping itself. Get your weight behind it and either use 2 hands or have your body against the butt of the gun. It's the only way you are getting consistent sinks, at least in 40+ year old fir framing like I have. I have some fresh framing too and screws went in a little easier, but still required some grunt. 2) Your drywall piece needs to be firmly against the framing before shooting a screw. Get a helper or find a way to push the panel against the framing you are about to screw into. If you don't, the head will just go right through the paper. Screws will pop through the face paper if there is more than a 1/16" gap between the drywall and framing. 3) Keep the gun perpendicular to the drywall. It can shoot screws diagonally, but it won't sink them and you'll need to go touch those up later. You might as well use a drill for those since you will be hitting them with one later. 4) This thing is not good for inside corners. This is actually the only reason I gave 4 stars instead of 5. It doesn't fit well into corners, and it tears up the paper on the adjacent drywall panel if you do use it for the edge at an inside corner. So there you have it. I completely understand why some people gave this thing bad reviews. If you buy it expecting it to make you hang drywall like a pro, it does nothing of the sort. In fact, unless you are willing to spend an hour or two getting acquainted with it, you should just use a drill and drywall bit. Once you do get the hang of it, you can shoot screws ridiculously fast and it speeds up the job a lot. By the end, I had a good 90% of the screws going in properly with this thing, which is pretty good considering how much variation in density my house's old framing has. I have done various drywall projects in my and relatives houses for years, and always used a regular drill with a drywall bit. This screw gun was a good purchase and really sped up my garage finishing job, even accounting for the time I had to spend getting the feel for it. Helping my friend do her 20x30' garage in a month or so will go much faster with this product. Hopefully others will find my experience helpful. It was frustrating at first, but I knew that the problem was more with me than the gun so I kept at it and it paid off. September 10, 2014
Rated 1.0 out of 5.0 by Not worth the money I bought this collated screw gun and returned it because it did not work very well. After a careful set up according to the directions, it would not always engage the screws, it would fail to fully screw the screws into the plywood underlayment and plywood subfloor (a total of 1 1/8"), and it's clutch was inconsistent to the point of either incomplete screw insertion, as noted already, and it would snap off the Senco screws. Perhaps it was just this particular driver, but I was unwilling to bother with another one of this brand. March 20, 2015
