It's probably been about 20 years since the last time I used canned compressed air for anything but I remember the stream of air being more powerful. This got the job done and is probably perfect for delicate electronics tasks like blowing dust bunnies off a motherboard. I'll admit I used this to clean bread crumbs out of the bottom of a toaster. It worked... but next time I'll get an attachment for my air compressor to do it. Would have gone 5 stars but the trigger is a bit clunky. I actually pushed one it right off the top of the can when connecting the straw the first time! Easy to put back together though.
Bought this product recently as one of my power amp "died" and once I opened it I was greeted with a huge amount of dust.This product removed 99% of it from the circuit boards caps wires and fuses. Once was cleaned I was able to spot the issue with the amp: one of it's internal fuses was blown once replaced it was back on duty. After that I opened all my audio amps and cleaned them with this product also cleaned my desktop PC. This product is or it's peers a must IMO for PV and electronics cleaning maintenance The only reason it's not 5 star as the pressure falls quiet a bit after a few longer 15sec bursts. When that happens one must let it rest a for awhile to have the pressure to return. I don't know if this is brands specific of this is how these products work. They also get very cold to the touch but I assume this is normal. Other than that I think they are very effective.
So far it is doing fantastic - I have several items that I use it on and they are all working great. I like to clean my digital equipmen out at least once a month when the furnace is running during the winter.
