Multiple uses for canned air and the power is good. I use on my coffee maker to unclog lines and computer stuff among other uses. Great to have around the house.

Good price for 4, but not much air per can, and 2 out of 4 can the air blow out is weak, i have to put them into hot water for couple minutes to increase air pressure.

DO NOT use without wide open space, smell is AWFUL, takes your breath away, taste & smell over power you. 1 can blew out while just sitting on the counter. Had to air house out, it was SO STRONG. WILL NEVER BUY AGAIN!

One can had no air in it, empty!!

I like that you don't have to shake the can. If used steady it will be to cold to hold.

Last 2 purchases, 3 cans didn't work. Received full refund but quality is poor.

SEEMS TO WORK WELL FOR CLEANING DUST OUT OF ELECTRONICS...WHICH IS WHY I GOT THIS ITEM...DUST BUILDUP IN DVD PLAYER..

Came in a 4 pack each one with a red extender tube. Shipped fast via FedEx. And, you can't beat the price.

Love this for my computer keyboard, works very well getting into the tight spaces and clearing the debris (food, crumbs, etc.) out.

The first can out of the package would not spray! This is to expensive to have one not spray!
