I always suggest to anyone who buys any hydraulic tools from HF to go ahead and buy their extended warranty. Most people I know have had decent luck, but now and then a tool fails, and they are difficult to get repaired.
In fact, I advise people who are buying any tool with motor, pneumatics, hydraulics, or lots of moving parts to buy that warranty. HF wants to sell those warranties so much that, when something fails they don't CARE why. They replace it with no questions asked. Just figure that cost into the purchase price.
