GemRed Digital Level Angle Slope Pitch Measure (YD-I Level with Magnets 200mm)

Instructions show a unit w. bubble vials. This one missing them. Also, doesn't indicate how to change battery. Minor item but I'm used to removing screws from instrumentation not grabbing plastic in the front and seeing what gives. A little more ink on the IB (instruction bulletin) would go along way to getting to USA standard for electronic devices. Still, it's nifty for the price.

Does the job, cheap plastic not the best materials on the unit.

love it

Perfect tool.

Not accurate, if i measure the same thing 3 times i get 3 different readings.

Does not accurately show slope in percentage.
