So I've been wanting one of these for a very long time because I periodically buy compressed air but I think that they are completely wasting money or just one or two little things you literally charged up as much as you want and there's tons of air pressure. As you can see from the picture there are tons of attachments and brushes that come with this for doing deep cleaning on just about anything. I've used this everywhere for my car, computer, laptops, cell phone, odds and ends, tools and everywhere else that I can pretty much blow dust out of. It also works very good on fans too. I've had a tower fan and I haven't cleaned or dust it out and probably 5 years other than wiping off the outside portion but not really knowing how to clean the inside and this thing literally made a dust storm when I finally got around to cleaning it out and now I feel like it's working up too far and good as new again. This thing basically has three different air settings and then off so you basically hold down the button for about 2 to 3 seconds and it switches mode from low medium high and then off. And if you double click it it will actually turn the flashlight on and off so you can actually have a flashlight at the same time. This thing takes quite a bit of time to charge up because it's got a huge amount of battery juice and seems to last for quite some time on one charge. Basically has three different nozzles the one that has a bigger hole and a brush on it. One that has a more cone shaped and then it also has like a weird nozzle that's got this thing on the top that kind of splits the air so it shoots up and down. So far all of them and came in handy. It also has a nice little Crossing bag and a USBC cord and three different small types of brushes. It's got like a regular kind of bristle brush that you would find and a package of the wire brushes or the brass brushes but this is just working with plastic bristles it's got a longer flat brush that's kind of a harder verse old one that you can use to really pick up some Grime and then it's got a small detail kind of brush. Overall I highly recommend this thing and it's very affordable. And this thing comes in handy just about everywhere. I can think of a million different uses like cleaning the TVs pretty much any of the electronic, cameras and things of that nature. I also do want to mention that I am a very huge fan of the knf concept brand and I have a boatload of products from them but mainly lens filters. I've been doing photography and videography for about 10 years and I acquired quite the number of items on this company and I've been extremely happy with the quality of them. I definitely think that they are a bit pricier than some of the stuff floating around but 100% worth of quality and as soon as I seen that they had this I swooped it up as soon as possible.
