Chinese Manufactured Roofing Power Tools

Have any of you purchased and then used some of the Chinese manufactured power tools that are available thru Harbor Freight Tool and other American tool retailers. I often see roofing coil nailers priced at $69.99 and air compressors and/or electric generators priced at between $99.99 to 129.99. Just wondering if anyone has bought them and do you find them to be efficient and made to tough enough standards for working on roofs.>>>

I have also bought a few things from harbor freight and they have been ok thus far.>>>

I have bought some tools from them and for the price I can't complain. Flat bars ,hammers drill bits are all ok. I even bought a 18 volt drill for $29.00 and I could not kill it or the battery. It would last all day on a gutter job. I also got SDS drill bit set 1/4 to 1 for $19.00 that are as good as any I paid full price for>>>

I saw a similar deal at one of the big box stores. All I can say is you get what you pay for. Or, if the deal looks to good to be true then it probably is.

I don't know about the gun but you've got to look and CFM that these compressors deliver.>>>
