I bought this exact one off Amazon a little over a month ago. Used it a bunch of time swapping wheels on and off.
It works great. Easy few pumps to lift, low height gets under my lowered car easily, no problems with gradually lowering it back down. Plus it is very light (as far as jacks go), which was important for me since I get stuck carrying mine up and down a flight of stairs when I want to use it
I think it was worth the money.
