CleanSafe Dust Remover is essentially a canned air product. It is primarily designed to be used on computer equipment where cleaning is not especially easy, such as keyboards.
Of particular note is the fact that this canned air contains "bittergent" which, despite the name, is not related to detergent. Rather "bittergent" makes the air bitter, and is thus a deterrent for people who use products like this to achieve a dangerous high. I have only used this product normally and I can say it doesn't smell like previous canned air products I've used on my computers, but it doesn't leave a bad smell on anything either, and that's important.
The product is easy to operate, and it has a safety tab so you don't accidentally release any air before you have the product ready for use. It also means you can be sure that someone in the store didn't let air out of it either. One can can be used for several minutes, which is enough for dozens of cleanings of regular equipment like keyboards or inside of a dirty computer case.
Everyone should have some canned air. While it sounds like a frivolous purchase, it's not very expensive and will help you keep your computer equipment clean. CleanSafe Dust Remover is especially good if you have children because the "bittergent" will prevent them from accidentally or intentionally getting high during usage.
