I think I've only owned two products via Harbor Freight that haven't failed me.
Western Safety - item#96538 Pack of 3 Polyester/Cotton Gloves Pass/Fail: Pass mostly. Although these gloves have ripped at all, they are no longer as yellow as they used to be and faded pretty quickly. The SKU is SKU 96538 and these cost $2.99. They are made in China though.
Husky 9 Ft. x 12 Ft. Disposable Drop Cloth pass/fail: Pass 100%. Really did a great job not bleeding through the concrete when I did some painting and was very easy to work with. Made in USA this time and probably the only item I've ever bought there that I've had absolutely no issues at all.
http://www.harborfreight.com/electronic-repair-kit-67062.html 16-in-1 Electronic Repair Kit Pass/Fail: Fail. Wow these bits were not exactly as strong as I thought they would be. Several of the bits have either nearly snapped on me or have become nearly stripped.
There is a review on
www.Amazon.com about this kit and that review essentially encompasses my opinion on this set.

That is a Pittsburgh brand and the SKU is 67062. Avoid and if you did buy this, return it as fast you as can. I wish I did at the time.
http://www.harborfreight.com/caulk-saver-97561.html Caulking saver Pass/Fail: Fail, as this item snapped on me, either the 2nd time or so. Despite the fact this was designed in USA, but made in China, this was $1.99 I wish I spent elsewhere.
Grout Finishing Tool Pass or Fail: Fail, I had used this product maybe one time doing some grout work and this item snapped the first time. As I tried to tried to piece this back together, the ball end cracked and just wasn't worth doing anymore work in fixing this. Junk, avoid.
Pittsburgh 6" Diagonal Cutters pass/fail: Fail. The spring of this cutter was very loose to begin with and that took some time to put back into place. These cutters were dull to begin with, but after maybe using these cutters maybe 5-8 times, they became even more dull and sharpening these takes a great deal of time, especially if you don't have the right tools. Made in China, even the old stock which I do own. I actually took off the grips and plasti dipped them instead.
Combination Sharpening Stone (no name brand) Pass/fail: Fail. Not only did this not really sharpen any my tools, several months after buying this, I was using this outside and accidentally knocked this on the ground and this snapped in half. This only was $1 then, so that was a dollar lost.
I heard that Harbor Freight has a warranty on some tools, but after 90 days, that warranty is pretty void I've been told by others.
