Review (4/5): Plan on contributing to filling the landfill with AA batteries
Works as well as I expected however mine seems to use up the battery sooner than I expected so plan on buying batteries by the case. It must have a high power draw from the batteries or manufacturing defect but it does work well with a fresh set of batteries. If you use it 2 - 3 times daily maybe you'll get a month's worth of use before it starts acting up (it acts like it wants to start but only for a fraction of a second).
