HF jacks are definitely not the best quality out there, but for the money a decent deal. Just be sure to ALWAYS use JACK STANDS. I've had ones blow their main seal and so have others, but you can always exchange them for another.

I bought one, lightweight aluminum, to take to the track... works fine for what I need (changing wheels/tires). For the shop/home I would use a more trusty, beefy, jack.
