I've had a lot of different vacuums ranging from 1960s to modern and the Dyson I currently have is by far the best performing of any I've ever used. They're typically overpriced but I got mine on sale, I've had it for over a decade now and it's still going strong. I'd buy another one if I ever lost it.

If you go looking for a flashlight online you will find plenty of handheld flashlights with claims like 5000 lumen 10 000 lumen sometimes even 100 000 lumen... yet the thing runs from 2xAA cells. Since people have no idea how bright a lumen is they beleve the numbers... even tho it would take multiple kW worth of LEDs to actually get such lumens.

Many of the flashlights are greatly exagerated, however it would not take multiple kW of LEDs to reach those numbers. A 1kW metal halide lamp of the sort used to illuminate parking lots and sports fields is about 125,000 lumens. Recently these are getting replaced by LED lights that consume about 1/3 that.

Yeah Dyson is not junk, not even close, its just expensive. Anyone who says that has never owned or taken apart a Dyson product.

--- End quote ---

The "barrel" is an multiply-defined unit, depending on what product is contained therein.
see  https://en.wikipedia.org/wiki/Barrel_(unit)
The "bushel" is similar, and legal usage in the US seems to define it by weight of material.
As a unit, "buckets" are rare, but seem to be defined as 4 gallons, and the "gallon" depends on which country defines it.

Miles are bullshit. The USA uses 3 different miles that are close to the same length, but slightly different.
