Interesting video.
I'm a big milwaukee fan. Have quite a few of their tools for work and home.
With that said, i have not been impressed with some of the m12 tools. So i'm not surprised by those results.
I have the m12 ratchet (non impact) and i don't find it to be all that useful. If you are assembling something like a wheel barrel, table etc, it's great, but for bolts that have been on a car, pretty much forget it.
The small m12 batteries are useless in the majority of tools. I mainly use them in flashlights, laser plumb bob and the small hex impact driver (which is probably my most used tool).
So if you buy m12 tools, only purchase when they come with a free upgraded battery (which is very common) i'm not sure how much more power they give you, but from using my m12 hackzall all the time, i can tell you it's alot.
Just keep in mind, if a tool has an 18v version, opt for those instead, which for the most part, i find unstoppable.
I did purchased this m12 tool recently and i love it.

I haven't used it to fill a car tire yet, but i'm told it works good, but i've used it on all types of sporting goods and yard equipment.
My extremely loud 30 gallon air compressor is getting less and less use, which is fine with me.
