Now that I've had a chance to let the unit charge, I've come back to edit my review. No instructions are included in the box. This isn't necessarily a huge problem: there is one button on the unit, and holding it down turns the blower 'on.' Letting it go shuts it off. It really can't get easier to use.

However, the online manual notes that the device should be charged for 10 hours before using, and a reference to this suggestion should be included in the box. The wall wart has an LED that shines green when the unit is charged, and red while it is charging; it took a little less than five hours for the light to go green on its first charge.

The duster definitely moves some air. The manufacturer claims airspeeds of 200 miles per hour; the air coming out the nozzle with or without the focusing straw does not feel as though it is moving at that speed. Comparing with a chemical air-duster, the chemical product does seem more powerful. The nozzle is also much smaller on the chemical duster to fit into the fins on small heatsinks.

However, the ability to run the electric duster for extended periods without filling the room with chemical vapors and bittering agents is a definite plus. While it does emit a high pitched whine while running it reminds me of a dustbuster hand vacuum I'm so far happy with this purchase.

I repair copy machines for a living. It has really been nice to not breath in all the chemicals from canned air. I carry both in my bag but have not used the canned air since I started carrying the O2 system. I have even suggested that we replace our canned air with this unit. My machines are cleaner and I can use it at any angle. Try doing that with canned air.

I didn't get this so much for my keyboard as for the collections of knickknacks that crowd our shelves. Wow, I was very impressed with how it blew the dust away. Yes, I know the dust in still "there," but I assume it will drift down to some flat surface where regular dusting and vacuuming will pick it up. Care must be taken on light items (little wooden carved animals from Oaxaca Mexico), because they will be blown over in the gale -you need to back away some with these types of items.

So I'm very pleased and wish I would have discovered this years ago!

I knew this product might not be what it was cracked up to be when they measured the air flow in MPH, and not in PSI, CFM, or SCFM, and they did not make a comparison to how it measures up to canned air in this regard. Basically this is just a small fan that blows air. It's force is maybe a little more than half of what canned air is. It is also very noisy due to the high RPM the motor has to run at to generate wind speed from the small internal fan. I rated this at two stars because it does work, but ONLY for very light duty uses. It does not have the power or force needed to remove fine dust particles or larger debris in tight spaces where you can't get right up on. You can also feel a reduction in air flow when you use the straw extension due to fact that the small motor can't handle the added resistance the straw adds. For what you get it is also a very pricy unit. I do a lot of electronic/computer work and it just did not fit my needs. I decided to return this product and bought a small electric air compressor at the local hardware store. It was cheaper than this product and has even more force than canned air. The only downside is it weighs more, but is still portable enough to not be an issue. I also can use it for other tasks other than just cleaning, which to me makes an air compressor an even greater value. For some, this product may work, but for me it just was not economical nor forceful enough to be worth while.

Purchased this because I was tired of buying the compressed air type cans, to clean off my keyboard and computer, every month or so.

Pro:

Rechargeable battery included

Will run continuously for longer than I usually need, won't crap out like the compressed air cans do after 20 seconds or so

Basically the same size as the compressed air versions

Con:

The only con that I have found is the noise that it makes, I have to be careful not to use it late at night, otherwise it might wake up the wife and kid. This was enough to take a star off the rating, otherwise it would have been a 5-star product.

Still glad I purchased it as it saves me money and does the job just fine.
