I'm tired of paying for literal fucking air. Tell me about electric air dusters. Since a can of compressed air is like 10 bucks, I'm thinking this thing will pay for itself in a year tops even if you get like a 100 bucks one, but is it as good? Are you fine as long as you avoid the cheapest shit or do you need to buy some professional multi-hundred dollar one for it to do its job? Or is a plug-in compressor the only affordable alternative to canned air (if you don't need to travel with the thing)?
