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.
This product works well enough due to sufficient pressure of the propellant. There is no smell as the aerosol removes dirt as it is supposed to do. The only issue is the nozzle extension does not attach well. It has flown across the room on several occassions. Otherwise it works well for the price.
