I'd have thought that someone with your intellectual superiority and ability to use the Internet machine would have been able to do a few subsequent "minutes of research" to check your facts. Couple that to the use of some simple reasoning skills and you might have gotten somewhere.
The unit I bought is rated at 2600 lbs each, first of all.
Two will give a capacity over 5000 lbs. The ability to lift a vehicle with a frame is of no concern to me as then there IS plenty of length to use jacks and jack stands and support it completely. So it's moot.
And of course, you fail to address the major item, the ability to do suspension work with the wheels off. Let's do a "couple of minutes of research" and verify the hassle of doing that with a kwik lift. So you have a glorified set of ramps that go a little higher. Plus the need to still hassle with a hydraulic jack. If all I'm doing is oil or other simple under the car work, I'll take the simplicity of ramps any day. If I need wheels off, the kwik lift just doesn't deliver in a useful way.
Seriously?!?
But did I disparage your equipment like that? No. I did shop that amongst others. And found it limiting, and bulky.
The two known failures of the ez car lift were design issues coupled with user error. They are well defined and the owner will discuss them and the mitigations. The one other thing that will pop up with a"couple minutes of research" is someone complaining about asking for discounts. Boo.
Why not help guide the OP based upon real research and decision processes, instead of chest thumping over your system by disparaging others'?
So yet again in your futile attempts to show your superiority, you fail. Why a 70+ year old who has supposedly "made it" and whose every action is so superior to others has to act this way is beyond me. I'm half your age or younger. Amazing that I have to say these things.
