The plastic is junk; I bought a dozen of them when they were on sale for $.99 each. Within two months, I was down to just two of them. This is one product that I say "STAY AWAY" from.M8A9

it works for a cheap price

I've got two of these and both of the will leak from somewhere. I took one apart and replaced the o-rings, and it still leaks from the valve inside and I cannot see why. Not all the time, either. Sometimes it sits there and behaves itself, then out of nowhere it starts to hiss. Really irritating. Outwardly it is a nice design, seems durable, gets into small places just fine, but there are much better ones at Harbor Freight for another buck.

Cheap is the word. The plastic is of poor quality so after a little while the body cracked leaking air but somewhat usable still. a little while later it stopped working one day. Never did get it to work again. So in the trash it went. But for quick clean ups and blowing off dust in a workshop it served its purpose, light on the wallet too. I went back and got a simple pin sized blower and hasnt let me down, and would honestly suggest you just pass on this if your looking for something to blow down the workshop.

We use these on our CNC machines for blowing off chips from work. Don't over tighten the attachment otherwise it will break the air connector port.

cheap and seem to be pretty sturdy. Not OSHA rated for sure, but great for those tight places.
