harbor freight tools?????

We also have a H.F. store nearby and I have the opportunity to at least look over the stuff before I buy it. I've got a cut off tool that I've used for about 5 years now so no complaints there, the 3" discs they sell for it are as good as any brand I've used. As said before, the paint gun is good for primer. I've also got a couple other air tools from them (3/8 air rachet, shear & nibbler) that I've not used enough to assess, although they did the job I bought them for. I have used several sets of the quick couplers, they don't seem to last too long. I don't know why I keep buying them???
