I have the Trailer Aid + and have used it twice over the last 12 yrs or so. Also use a 12 ton HF bottle jack. Here's the how and why I use each.

Trailer Aid Plus - that gets used for changing a tire on the side of the road. With using that (and a Dewalt 20 v impact gun) I can change a tire very quickly with the least amount of bodily exposure to traffic. Typically a roadside tire change will not be conducted on a level surface. The ramp won't shift or kick out and no concern gor a seal failure causing the jack to collapse rapidly.

Bottle jack is used for any and all maintenance and repairs. Typically when conducting R & M the surface is fairly level and stable. I use the bottle jack to lift and wood cribbing /jack stands for support.
