If you have a Costos membership, they have a great deal on a Screwdriver Set with both a T5 and a T6 plus more for $8.97, great if you are looking for extra screwdrivers.
or you can simply go to sears and get a single t6 for $3 and it's a good one lol. Harbor is bottom of the barrel. I have lots of harbor tools, but it's all disposable lol. If I were making a living with tools, they wouldn't be a thought, but stuff that gets used 2-3 times a year, ya can't go wrong...I just had to fix a juliet with a totally rounded screw, and I am sure the driver played it's role on top of the super soft trash screws oakley uses.
They did have some Oakleys glasses there, though no sunglasses. And i never thought the screws that Oakley used in the Juliet were weak, I know the screws in original PSP were as good as butter... The only good thing about Harbor Freight Tools is the lifetime warranty with no receipt.
