I have a few ( non Dewalt) . Used to keep one in each work van incase we needed a blow gun. we would use them to blow off chop saws and compressors if we had to haul it thru a carpeted apartment hallway floor or something like that
They are fine, nothing wrong with them. but for continual use I probably prefer the grip style .but these are handy to have as they don't take up a lot of space
