I bought some metal loading ramps at Harbor Freight. All of the edges on the ramps were razor sharp, probably because the ramps were stamped and no effort was made to dull the sharp edges. Not surprisingly, I cut my hands while attempting to use the ramps. So, I boxed them up and put them in my garage. Because the ramps were defective (sharp edges) and unusable, I tried to return them to Harbor Freight. The manager told me that it had been more than 90 days since I bought them and Harbor Freight would not give me an exchange, refund or store credit. Harbor Freight sells highly defective products. I will never buy anything from them again and encourage others to do the same.
