Work straight several uses out of one charge. Wish there was a way to lock the tip in place comes off way too easy. Probably have to glue it in place.

Bought a 180,000 rpm. Got delivered a 130,000 rpm one in a damaged box. Took it out, and it wasn’t even working. Disappointed.

This Electric Air Duster is totally Awesome. I use it to clean my robot vacuum cleaner with and it does a great job. It puts out alot of air pressure so it is perfect for dusting off just about anything you can reach with it especially for example those tight spaces in between the keys on your computer keyboard or even for dusting your Ceiling Fans off if you can reach the blades and the main parts of them by hand. The battery life is great and it is worth the money.

I have a few of these air compressors and they seem to get stronger and stronger with new ones. This one is no different - it seems very strong and maybe stronger than my strongest one - but it's close. This seems to only operate with the button pressed. You first have a button to turn it on, and then another button for the intensity. Either way, you can't have it blow without you pressing the trigger so you can just have it on (or at least I haven't found out how to do that). But that's not a huge deal - I'm not typically using these in more than a few seconds burst. What I am a little surprised is the lack of nozzle attachments. There is none - except for the cone that is already on the duster. It's probably OK for most applications but I usually see a number of extra attachments for these air compressors. It's strong and feels sleek and simple. No case because you don't have any attachments anyway to put everything in. Is it more powerful that canned air? I think it's debatable. Actually, no I can say is it not more poweful in terms of short bursts, which is what these are usually used for. Canned air is instant pressure. These air compressors take a second to get up to speed. That said, I think it's a good alternative and is more than enough for most of our applications.

I ordered this to use in cleaning/dusting my keyboards and other electronics. It works well but I think it would work much better if it came with some attachments like a brush or funnel that was smaller. Overall it was worth ordering but I'm sure there are other options out there that have some better features.

I got this because I didn't like having to buy canned air at 2 to 3 bucks a pop and I use a fair amount of it on computer keyboards and so forth. This seemed like a good idea. And indeed for that use it is very good. And I'm perfectly happy with it. It does have several problems that detract from it being a five-star item. The first is that it's overpriced. There are lots of other battery run blowers that are similar, and several that look identical for considerably less money. Currently listed at $90. It comes without accessories and several other similar dusters have what look like useful accessories. I would think this would be helpful for blowing up an air mattress for instance, however it doesn't have the adapter for that. It does have a magnetically attached nose piece, and I think the idea is that other magnetic pieces could be used in place of the one supplied, however there aren't any with this particular setup. Additionally there appears to be a quality control problem with how the nose pieces attached, it appears to work in several different orientations, however when you look closely at it only one orientation does the mating of the nose piece to the body work well, all the other positions leave gaps, losing some of the air out the edges. All of this is complicated by a poorly written and translated manual. For the premium price of this particular item I would hope that there would be a useful translation. The manual seems to indicate that there is an automatic mode in which at speeds one and two the blower will stay on until you turn it off, I spent a half an hour trying to figure out how to do that and it doesn't appear that mine has that function. Additionally the manual says that it defaults to speed three after turning off, well that is technically true, however you have to leave it off for 15 minutes or else it restarts at whatever the prior speed was. I think this is just fine, however the manual is very confusing as it doesn't say that. The advertisement on Amazon shows it being used as a garden type leaf blower, it does blow an impressive amount considering its size, however it is nowhere near the strength of my 15-year-old electric garden leaf blower. That did however give me an idea of a very practical use for this blower, that is using it somewhat like an outdoor leaf blower but in my kitchen. My kitchen gets a lot of traffic and a lot of little bits of dirt and stuff on the floor and using this blower like an outdoor leaf blower to blow all the stuff into a corner then sweeping it up is actually quite a bit faster than sweeping the whole kitchen. Anyway I kind of like that use for it in addition to its use as a replacement for canned air. Besides using it on keyboards and such, it also helps to blow out the chopped up whiskers at my electric razor generates. Anyway I actually like this blower quite a bit but it has several annoying problems that I spent quite a bit of time on ... wasted, trying to figure out the discrepancies between my usage and what the manual indicates.

This thing is NOISEY. My dog went running and is now afraid of it. It is very powerful and I've found uses for it. I wish it came with more nozzles to attach to have a more direct stream of air. It is hard to control the flow with the nozzle it comes with. Unfortunately, not good for smaller projects.
