How does the WatrLevel compare to other water levels?
There are essentially three types of water levels available: without a reservoir, with a reservoir, and electronic. The type without a reservoir is either two clear pieces of tubing attached to the ends of a hose or just plain tubing. They are typically cumbersome to use. The type with a reservoir is easier to use because of the reservoir. Both types will only provide a level reference line, not measurements and both are cheap to make/buy. The third type, the electronic version, will beep when you lift the tubing and the water reaches the level in the electronic reservoir, again only providing a mark, no measurement.
