Hand tools are fine 99%. Cutting tools–the part that actually does the cutting–are usually fine. Power tools are very hit or miss. Like, I would definitely not buy any cordless or corded tools there. Air tools are generally okay, but don’t work as well as other, more expensive air tool brands. OTOH, I’ve used a Harbor Freight flooring stapler that failed in under a day of use, while the Husky branded stapler did just fine for a few years. Impact sockets are good, although they’re limited on sizes (I don’t think that they have anything bigger than 22mm). I’ve been using a Harbor Freight floor jack and jack stands for a few years now without issue.
