I have had horrible luck with harbor freight tools. I stopped buying them. I tend to stick to Craftsman or Dewalt now. I've had great luck with both of those brands.
I have some tools from Harbor Freight (father in law bought for me). They are alright. I prefer to stick with Dewalt, much better quality. I don't like to buy tools that only last a short time.
We bought some tools from Harbor Freight for my brother in law. He said they were fine. We bought them last year. They are still holding up well. I would say if you plan on using the tools all the time, I would buy a better brand.
