MG Chemicals 402A 134A Super Duster, 285g (10 oz) Aerosol Can (Packaging May Vary)

This product should just be called "No Bitterant" because that is the only thing that matters. Why? Just go ahead and buy some other normal can of compressed air, spray it on your finger, and then taste it. Yep, that is officially the most disgusting taste in the history of the world. It's caused by an additive called bitterant that prevents people from huffing this stuff I guess. I have no idea why someone would huff air, but I do know that the bitterant has rendered basically every compressed air product on the planet totally useless. This product HAS NO BITTERANT. So when you spray it on something like the most obvious use case - your keyboard - your fingers won't pick up the nastiest tasting residue in the history of the world. So in summary, it's a good idea to pay the premium for this duster or else you'll be paying the price later in straight up nastyness.

Awesome

This item freezes so fast it is not worth your trouble. I have used many compressed air cans this has been by far the worst for use a freezes so fast - thank goodness I bought 2 and was able to switch off - stinks that I couldn’t save as planned

I'm not sure that this is the right product for my needs. (I have not used it yet, but you must enter a star rating in order to enter a comment.)The description here says it can be used on photographic equipment and keyboards but the writing on the can says:"For Use With Energized Equipment Only" & "Use only where electric current exists, residual electronic potential from a component such as a capacitor exists, or an open flame exists. For all other applications use Super Duster 152."I even went to the MG Chemical website, but the description there is the same for both products.

The perfect duster, except for the price. Remember when canned air used to be less expensive than refrigerant? Sigh. Now most canned air leaves a stinky bitter residue behind. Not this stuff. This is what they all used to be like, except this is at least 2x what it should cost. Check out R134a 12oz cans...

I've found this canned air powerful enough to blast away almost anything in my computer keyboard and other hard-to-dust/clean places.The can does get awfully cold when used, though. You might want to wear gloves if using it for a prolonged period.

Runs out to fast , and the can gets super cold can not hold for more then a minute

r134 duster, can be used like super cold if held upside down
