Title: Very Smooth Very Simple
Review: Works great, very smooth and quiet mechanism. No leaks. Great value for the money.The selection for length of operation has a plastic taped decal applied to a timer wheel ...which may rub off under use, exposure to sun or weathering. I applied a clear coat paint over it to extend the life of the lettering.It seems to turn off after a maximum of (I believe) 3 hours .... the "Always On" position remains a mystery to me as to how to set it. Have used device about 3 times.
Is the review positive or negative?
