Title: Not worth the trouble
Review: I bought this because it advertised on the packaging that one person could use it (generally not the case for waterlevels). The problem with this one is that it seemed virtually impossible to get anything level. The above/below sounds is too similar and the unit doesn't seem to ever give you more than a split second indication of level after which it starts making other noises. Hence the reason for buying -one man job- did not work out. Returned the unit the same day, back to the old tubing for me. An additional problem with this unit is that it's high pitched beeping is REALLY loud in a confined space.
Is the review positive or negative?
