Not a product I usually purchase but seems to work fine...pretty much as you'd expect. Sufficient stream of air generated and a thin attachment provided to direct the air into small crevices. Giving it 4 stars because seems a little pricey to me. Seems to me you should be able to make this product at half the price.
Haven't used it yet but I am sure that it will work like all the others. One thing I did notice that if I had read the can I would have gotten another produce. This stuff is very flammable where the other product I use is not.
