WOLFBOX MF100 Electric Air Duster-150000RPM Super Power Cordless Air Duster, Rechargeable Brushless Motor Durable Blower, 3-Gear Adjustable Dust Blower for Computer, Keyboard, Outdoor, House and Car

I was really skeptical of these things in general, but if you watch the Torque Test Channel on Youtube like I do, then you'll know why I finally bit the bullet on the Wolfbox. I initially got the no-name runner up from TTC's first air duster shootout video (the "Mershgaya" store sells it on Amazon, so I'll be referring to it as the "Mersh" from this point forward), since the Wolfbox pretty much immediately sold out right after that video went live. Ended up ordering the Wolfbox about a month later when it was back in stock, and let me tell you, there's NO comparison in build quality, battery life, air output and control setup/user interface. Having used both of them now for about 5-6 months, I'm going to use this opportunity to compare them and tell you why the Wolfbox is ABSOLUTELY the better choice, for only about $20 more (seriously...don't bother with the Mershgaya). NOTE: I am NOT a shill for Wolfbox. I paid full price with my own wallet for both of these dusters, and this is 100% my honest opinion on both units. I have not been compensated in any way...neither company even knows I'm typing this right now. So with that said, read on.1. Build quality: The Mersh is very large in-hand due to its huge cylindrical battery compartment/handle, but feels light and looks like it's made from very inexpensive plastic. The buttons and rotating speed adjustment wheel feel like toy-level quality...ie, cheap. Do they work? Yes...but they do not inspire confidence. The Wolfbox is a completely different story. Compact, fits well in the hand, and feels incredibly solid. I wouldn't advocate dropping either unit, but the Wolfbox feels like it would survive a fall 10x better than the Mersh. Well detailed handle, rubberized grips, solid feeling buttons, no wonky/unnecessary adjustment wheel, and the nozzles have a set of locking tabs built into them that allow you to rotate them to lock them into place. The nozzles on the Mersh are just a friction fit that will likely wear out over time.2. Battery life: this is where I really noticed a huge difference in performance between the two units. Quite simply, the battery life on the Mersh absolutely sucks. No other way to slice it. Using it on it's highest speed will drain the battery very quickly. It's not like I use these things all day every day so I can't put an exact time to it, but with similar levels of use I've had to charge the Mersh about 4x more often compared to the Wolfbox. That large battery compartment in the Mersh's handle is clearly hiding some big, bulky, low quality cells. The Wolfbox's more compact design clearly uses newer, higher capacity cells that are much better regulated. I've only had to charge it twice so far in 5 months!3. Air output: This is a little more subjective in day-to-day use, but when you put them side by side, I can definitely say that the Wolfbox has a higher output. Will this matter a huge amount for about 95% of the folks who are looking into buying one of these? Doubtful. As far as tools to clean dust/dirt/sawdust off of things are concerned, I doubt most folks would notice a difference between them. However, if you're a machinist or metal worker who's clearing heavier chips/swarf off of your machines or blowing off a lot of metal powder from grinding operations, you will likely want the extra oomph that the Wolfbox has. Even if they were dead-even in output (which they aren't), I'd still recommend the Wolfbox for the better controls/build quality.4. Controls: Here's the crux of the issue for me - the control setup. Most of us who want to buy one of these things are used to using an air wand or blowoff nozzle connected to shop air, right? Press the lever, and you get a full blast of air out of the nozzle. Well, the Mersh doesn't mimic that same functionality. You click the button once, it goes to low power. Another click, medium. Third click, you're finally on high. A fourth click turns it off. Or, you can press and hold the button for a few seconds to activate the speed control wheel, which is honestly kind of useless IMO. It takes 4 or 5 revolutions of the wheel to go from 'off' to 'max', which is a little silly. I can't think of a single task where such a fine level of speed control would be necessary, but YMMV. I don't use it.The Wolfbox though? Simple setup. Hold down the button at the rear to power it on, then press the trigger and BAM. Instant full speed, max air flow. Let off the trigger and it shuts off instantly - just like you'd expect out of a blowoff nozzle connected to shop air. And this thing really moves some air, too. It does have an automatic mode with three speeds similar to the Mersh's default settings, so you can long-press the power button to power the unit on, then short press the same button to select the speed you want. After that, you can click the trigger to turn it on, and it will stay on until you click the trigger again to turn it off. You can adjust the air speed while it's running by clicking the power button, and there are LEDs that let you know which speed you're on. This is really useful for inflating pool toys, air mattresses, etc using the included inflation nozzle. The biggest thing to me though, is that instant on/off at max power when you first hit the trigger. They programmed the Wolfbox right out of the gate to function like a traditional shop air nozzle, so grabbing one of these and adding it to your toolbox will be a really easy transition for most guys/gals who are used to having air lines dangling all over the place, lol.Will one of these replace shop air entirely? No, of course not - that's not what they're designed for. But, not having to fire up my compressor and wait for it to build pressure just to blow something off has been a real game changer in my home shop/garage. These are very cool, super convenient little tools when using them for their intended purpose.If you've made it this far, thanks for reading! There may be a better cordless air duster out there, but if there is, I haven't seen it yet. The Wolfbox is definitely worth the money over pretty much anything else in the $50-$100 range right now. It's a beast. I will probably end up ordering a second one to replace the Mersh in my office. Hope this was helpful!

This thing is a beast! Having tried a number of battery-powered dusters, I was prepared for another underpowered device that would go back as a sad little return. As you probably guessed by the 5-star rating, my expectations were dead wrong.My #1 concern is power for a small form-factor duster. It needs to replace compressed gas cans, or it’s of no use to me. Not only does this thing do the job, but there’s no risk of losing power due to chilling. The medium speed is enough for most cleaning tasks. The high speed (let’s just call it “Turbo speed” is powerful enough to put dust into low Earth orbit. (No?) Kidding aside, it performs as well as the canned gas at first, then continues at the same power level long after the canned stuff would have quit. Score one for the Wolfbox.After meeting the power requirement, it still needed to be small enough to take with me on the road. As an architectural photographer saving space is important. The larger an item is, the less likely I am to have room for it on the road. No problem. The Wolfbox is smaller than a can of Dust-Off. Another point scored.Will it last? It feels solid. Everything about the main body construction appears to have been well thought out. Heck, it just feels right. Let’s give it another point for not feeling cheap.Finally, let’s address the elephant in the room. Can something this small have a battery that lasts long enough to outperform canned gas? YES. I haven’t tested the blower just to run the battery down, primarily because I haven’t run out of juice while trying to use it. I assume that “Turbo mode” chews through the battery quickly, but since it outlasts at least a couple cans of compressed gas, it’s not really a concern. At either of the two lower speeds, it’s not even a fair fight. USB-C charging makes it convenient to keep ready for use. Yes another point for the Wolfbox.The one accessory I would love to see for this is some kind of filter for the air intake. To keep airflow to a maximum, any filter attachment would have to use a filter area significantly larger than the intake itself. Since I use this on photo gear, I may rig some kind of filter media holder. Not really sure yet.It’s not cheap, but for the price, size, power, convenience, and more, it’s an easy favorite as a portable blower.(Oh yeah… attachments! I suppose you might want to use it to inflate an air mattress, pool float, or some other large bag of emptiness. The accessory attachments seem to have everything covered. I might have to try it out on something just to see how it performs.)This is finally an battery powered blower that I will NOT be sending back!

Why did you pick this product vs others?:I got it to blow dust off slides and negatives when using my camera and macro lens for a large copy project. It works very well. I use full power with the oblong nozzle. A one second blast on each side of the slide pair in the JJC holder usually gets the dust off. I copy about 225 in a batch, then take a break. This uses about 1/4 of a full charge -- better than I expected! The unit is comfortable to hold and gets slightly warm towards the end of a session, which takes about 1.5 hours with the unit on standby and ready to use almost the entire time.It would be convenient if the unit could work off the charger only, but the battery life is so good I don't find this a problem for my use. The nozzles are not easy to twist and lock in place, but will probably get easier after they are installed and removed a few times.I considered canned air for this application, but rejected due to the toxic chemical propellent that I didn't want to breathe, and the environmental waste from the leftover cans. I also considered a small compressor setup, but found the cost and complexity too much. Even on sale, I think this little blower costs too much relative to other Chinese made products of similar or even more complex technology and materials. Regardless, if it proves reliable it will have been a good investment. Certainly easier, faster and more effective than the Staticmaster dust brush and Giottos hand Rocket Blower that I started the project with. Oh, and now I don't have to fetch my leaf blower from the basement when I just need to blow off the porches and steps. I'm going to find lots of uses for it. Cheers!
