i wonder how easy it would be to accidentally mess pressing the power button, only to push down on one side and spill everything.

the base seems very narrow

Yeah, this got my attention but haven't gotten around to reading/watching it.

Definitely got my attention for the "wow" factor. "Wait you mean instead of putting in 1 drop, shaking, looking for a color change, then another drop, shaking, looking for a color change, then another drop...etc, I can simply turn it on, put in a drop, and then another drop, and another drop until I see it change color?

Only concern is the gradation on the vial, I couldn't find a clear enough picture to see what the lines were at.

I actually picked one up recently but haven't had the opportunity to use it yet.

Is the test vial as huge as it looks? Or can you use your own? Wonder how small it can be and still work.
