Title: Way too much bitterant; freezes up & won't spray almost immediately
Review: My review title says it all. Even when held totally upright, the can is ice-cold to the touch within seconds. Who wants to spray freezing cold, icy air into their expensive electronics??? I should've listened to fellow reviewers who wrote of this problem. I guess you get what you pay for. I will definitely not repurchase. I've had two other brands of canned air, and neither were quite so bad as this, in freezing up so quickly. The spray action is rather minimal, even in the rare seconds it does work.
