Interesting. I can see an application where rolling a traditional floor jack over gravel/dirt/whatever is too clumsy.
Looks like many of these have about 16" of lift; but the red one weighs 43 lbs. The wheeled unit might be the hot tip.
In my shop, I'd rather use my traditional floor jack rather than fire up the compressor for an air jack; seems quicker & easier for that.
On an open trailer or restricted-access situation, though, it's either a bottle jack - clumsy, small contact area - or an air jack; I can see a benefit there if you have air.
We find ourselves in that situation fairly regularly. We buy vehicles with busted tires or damaged suspensions that are loaded with the fork truck onto our trailers. We use the scissor jacks from pick-up trucks to lift them. The jacks start at just a couple of inches high and with a battery impact and socket, they raise the vehicle up good and quick. Way better than lugging a floor jack or trying to fit a bottle jack under there. Plus the truck jacks are cheap ($5-$10) and plentiful. We probably have a half dozen or so around.
The air jacks start at just over 5" and go to 15" or so, which puts the lift at 10" +/-. That is probably my biggest reservation. 10" is not a lot by time you take up the tire's sidewall and relax the suspension.
The reviews on Amazon have people reporting that is doesn't take much air pressure or compressor volume to work the bags for most lifts.
