AIRROKI Compressed Air Duster

I was skeptical about products like these at first, which is why I have been on the fence and researching them for the last 6 months. I got this style/brand because some of the others required you to hold the on button for a few seconds to turn it on as if you didn't intend for that to happen while holding it in your hand. This one just turns on. The con to this one is that you have to cycle through a total of 3 power settings with the first one being the lowest...I'm reaching here because that is the only downside to this product. It is strong enough to blow dust and particles out from under laptop keyboards and regular keyboards. I've also used this in my truck to clean out the vents. I like the additional attachments, such as the one with the brush on the end of it. I really only use two, the one with the brush and the one with a smaller exit hole. That makes the stream more focused and can really move particles. I have not had it long enough to rate the battery life, so I will come back to that at a later time. I can tell you as of this review, I really am impressed and glad that I do not have to buy canned air anymore. I will just need to charge it for the next day.
