We sell a product at work, it's a circuit break of a very large name brand beginning with H. Made in Slovenia. They ran out of screws in manufacturing, so pulled screws out of something else and put them in (which didn't fit) and when you tried to undo them it stripped them and made them useless. We had thousands of dollars worth of stock in this product which was completely useless. Then another time on the exact same product, they ran out of springs for the test buttons, so just didn't put them in. That means the test button wouldn't spring out, so if you were to get audited by the electrical inspector you would fail from using that product. Useless!!
