Can you expand on that? I use my blowgun and inflator all the time with my small compressor. Both are very useful.
I have never had the need for one. I have a blow attachment, that I use for cleaning out computers, cleaning off the garage floor, but the inflator, is waste unless you are blowing up sports balls all the time, or have a pool, and blowing up pool toys all the time.
I just use a needle for sports balls, and the regular inflator when I need to inflate basketballs, which is rare if I do.
I can't imagine not having an inflator and blow gun. In fact I have two of each that I use fairly regularly. An old Truflate, I think it is, inflator with a gauge in the handle, which is real convenient for trucks, cars, trailers, tractors, etc., and a conventional inflator, for tighter places, like on mower and wheel barrow tires. Although I prefer to vacuum it up, sometimes it's handy to knock off some dust off of something just sanded, or whatever, and the OSHA approved blow guns are pretty good for that, without making too much of a mess, and the old pre-OSHA one is sometimes handy under the hood of a truck or tractor.
