I personally have the HF one. Although it gets the job done I really wish I would have spent some extra cash and gotten a better one. My biggest problem with the HF is how fast it drops. It feels like it slams the bike down every time. I always make sure I have somebody with me to steady the bike as it goes down the make sure it doesn't fall. If you want a lift you can reliably use by yourself I wouldn't recomend the HF one.
