For starters, there are minimum concrete slab thickness and minimum concrete strength requirements for any lift that uses any kind of anchor bolting to it. You'd have to verify that your floor meets - and preferably exceeds by a significant margin - those specs. Failing that they do, or that you cannot determine that they do, you get to chop out a couple of sections of floor and replace with a thicker slab that does meet spec.
My previous day job in engineering involved very much the same kinds of anchor bolting calculations that somebody had to do when writing up the installation instructions for these things, so I've got some idea about lifts. I've also seen first-hand where the matter of locating an anchor bolt too close to a floor seam or crack was about to be ignored by a professional installer on a commercial job.
Concrete failure modes tend to be very sudden, and with little warning. I was normally working with 12" or more of 5000 psi concrete, so just the thought that residential stuff may only be thin slabs of 3000 - 3500 psi concrete gives me the willies here.
I'm not at all against the MaxJax, and it at least appears to be possible that you would not have to disconnect the hydraulics if you plan your lift storage and setup sequence with that in mind.
I'd really like to see the EZ-Lift with better lateral support. Front to back it looks OK, but in the sideways direction I can see some stability issues once the pivot pins wear, if your setup area isn't level side to side, when you're set up outdoors and a wind crosswise to the car picks up, or possibly if you have to really pull hard on a wrench and you're pulling crosswise to the car.
There either is or was a sloping drive-on lift that works with a floor jack to level it after you've driven onto it. Undercar access is somewhat compromised, and the lift height is similar to the EZ-Lift. I think there was something about trolleys being available so you can lift the wheels clear. Forget the name, though.
