Since the ratchet broke on its very first use, I think it was probably defective. Try to warranty it and see how the next one performs.
But, perhaps they had a bad run. I wonder if your store would have similar ratchets from the same production run that may have the same problem?
This same or very similar ratchets are sold under the Kobalt, EZ Red, and Titan brands, as well as others. If they all failed so easily, I would think there would be more posts about them. I don't personally own them, but I think quite a few people here have the EZ Red version and perhaps the Titan version.
