Cordless Compressed Air Duster Compatible with DeWalt 20V MAX Battery (Tool Only), 4-in-1 Portable Blower Inflator Vacuum Deflator, 360MPH, 51,000 RPM Brushless Motor, 3-Speed for PC Cleaning, Air Bed

Awesome! Loved it within 5 mins of opening the box. Really powerful, tons of attachments for all kinds of different uses. Yes, its VERY loud on high with any attachments on the blower end. It has a very high volume of air that is being sucked in and the sound resonates to make a very high pitched, quite abrasive sound. I found a bit of a work around for that and will post pictures. Basically, you take off the regular back end cap and replace it with the fitting for deflation. You can actually "unscrew" the black hose from the fittings that are attached to it and either just use the cone shaped fitting with no hose attached or you can let the hose dangle if you done wanna take it apart. It makes a pretty dramatic difference in the noise and doesn't seem to make any difference in blowing power since the outlet on the front is not any bigger. When blowing against my arm, it still displaced the same amount of skin and hair. Its at least not enough to be noticeable. I may end up trying out some different filter foam to create some kind of diffuser but for now the deflator fitting works. Diffusing (or "breaking up") the incoming air changes the resonant frequency and can dramatically decrease all kinds of fan and blower noise and if don't properly, will not reduce air flow, just change its path a little. Another review, I think, said something about the plastic feeling cheap but I don't get that impression at all. I own many brands of professional power tools including dewalt, makita, and milwaukee and while this one seems to have a bit different "finish" to the plastic, it feels like a very solid tool. Ever since makita came out with a blower that is basically the same thing in their LXT line, I wanted it bad but they want something like $200 for their bare tool and I was just not willing to pay that for something like this. When I saw this one for this price, I jumped on it immediately since I also run many of the dewalt 20v max tools and have several batteries. Now for my only gripes, other than the noise thing, and they are pretty small and not even worth deducting a full star... maybe like half a star. 1. Needing to depress the trigger lock out switch every time for a non dangerous tool is a bit of a dumb design. It should have been a locking slide switch instead of a spring loaded "momentary " switch. That way it could be locked to throw in a bag or something and not have the trigger get pulled while bouncing around and activate the tool. Again, even if it did, it's not like its a tool with a blade or something potentially dangerous. Still, I was able to quickly adapt and work around it. There are ways to disable the lockout levers if one desires. 2. The batteries are pretty stiff and at least one of the types I have, the "compact" series 4ah (those are the flatter wider types) is so tight I probably won't use them. The XR packs are also a bit tight but workable. This will likely lossen up a bit with use or the rails can probably be lightly sanded or even use a bit of silicone grease but it still bares mentioning. 3. A true variable speed trigger with the three different speed levels would have been cooler to me than just the three fixed speeds and an on/off type trigger. Still highly usable though so not a huge deal. 4. And lastly, for me, a belt clip would have been nice to include. It has the slots for it so I may end up doing an after market one. Thats it folks. I don't do reviews that much but I was really excited about this little tool to replace the stupid and costly canned air in the house or when I'm not close to a compressor and I think it will do the job wonderfully. For the price compared to others on the market, it was a no brainer for me, especially considering, I don't think the makita version comes with nearly as many attachments. Don't quote me on that though. Go GET IT!

I bought this for blowing out air conditioner cabinets during servicing. Works very good. Super strong and blows hard. Several different tips included for multiple uses. My Dewalt batteries work great with it!

Blower works great and is powerful. I use it to blow out my garage floor, cleaning air filters and blowing off debris from stored items. My only dislike is that I have to press a safety button first in order to press the trigger! Why??? I have no clue…

Awesome, compact blower for the price! I am a professional painter, and used it heavily for blowing off sanding dust from projects and cleaning out my sanders and so on. It has great power for the size. The attachments are useful. It can last a long time depending on what AH battery you use. It's pretty loud but all blowers are loud to an extent so that doesn't concern me. This is my 2nd one I'm buying as the 1st one I bought finally bit the dust, literally. I think it just got caked up with so much fine sanding dust it's jamming the motor and making it 10x louder and smells like it's burning. So it's an awesome buy nonetheless! Especially if you're using it for cleaner job sites and tasks. For the money it's awesome I don't mind buying it over again as long as this brand stays on the market!

This blower works great. Just as described. It is well made and the attachments work well. I see a bunch of people complaining about the trigger lock, that you need to press, to press the trigger. It IS a pain in the butt. Especially for me as a lefty, since it is made for a righty. Guess what? Unscrew 8 screws and open the blower and remove the lock! It is just a piece of plastic and a spring. DONE! No more trigger lock. I don't know what so many people are complaining about. It took maybe 10 minutes.

I really wanted to like this cordless electric blower/vacuum, but it didn’t meet my expectations—especially for the price. It was exactly like another blower but they both had very different price points so beware. First, I was disappointed that it doesn’t come with its own battery. It relies on a separate battery, which drained mine quickly and made me concerned about shortening the overall battery life. The blowing power is okay, but not impressive. It gets the job done for light use, but I expected more performance at this price point. Another issue is the design of the controls. The buttons are stiff and difficult to press and lock into place. If you don’t have long fingers, it can be frustrating to operate. Adjusting the speed is also inconvenient—the button is located near the bottom above the battery and is hard to press. The weight of the item is similar to a large power screwdriver and so is the size. It is rather heavy when paired with the battery. Overall, it just didn’t perform the way I hoped it would. For the cost, I would prefer a unit that includes its own battery and offers easier, more user-friendly controls.

Works with my DeWalt 20V batteries, as described, and it's POWERFUL!! It'll blow dust off anything, but you should know it is very loud. That's the trade off for having it be powerful. It's crazy that DeWalt themselves doesn't make a product like this though. It's extremely useful.

Giving it five stars, but there a few cons you should be aware of. Pros: - Powerful! This is a leaf blower type motor that moves lots of air. Others were complaining that it didn't focus the air down to a small enough outlet. If you want that, get an air compressor. This is plenty powerful enough to do what I need which is blowing out electronics. - Well-built. This doesn't appear to be made of cheap, thin plastic. Appears to be ABS without any reinforcement, so don't expect this to be as tough as a DeWalt tool, but then it's not as expensive either. - Compact. The other alternative is an air compressor with a blower nozzle. Yeah, those are more powerful, but you can't carry it everywhere. For 90% of what I do, this has got it taken care of. - Trigger lock. With the round button behind the trigger, you just push it in and release the trigger. The blower will stay on - Versatile. The battery module is a separate part so they just change the color of the plastic being molded and the battery module and it will work with different batteries. The fit to the tool is VERY secure, though, as you can see from the pictures. - Flashlight. You're usually blowing around inside a computer with these, so having a light attached to the tool really helps. It also lights up all of the dust that blows out for that extra-good feeling! Cons: - Trigger safety = STUPID! that little lever you have to push in to get this to run is the stupidest idea ever. For fun, I took it apart to see how to disable it. You have to cut the bottom of that projection that sticks down from the lever off. Don't cut the whole thing off as you still want it in there to take up the hole. See picture. - Rough areas. Around the back of the spring loaded nozzle release, the molding was really sharp. I took the release ring off by pushing all the way back and twisting. I then filed it down. - Loose filter holder. The filter holder is loose and it will fall out when you bump it. I took a piece of thin cardboard and wedged it in there to keep it tight. - LOUD! You'd best wear ear protection with this. I used my noise-cancelling headphones and it worked even better to take the whine out of this. Sounds like a jet engine taking off. That's how you know it's working! - Loud. Did I mention it was loud? Final thoughts. I still give this five stars even though. With a little work, you can make it great, if just a little too loud to use without earmuffs. The color doesn't match the Dewalt perfect, but it's good enough for my tastes.
