Query: Attracts More Birds to My Bath

I have owned this little unit for over a year and it works great. Why? It is hard for birds to judge the depth of the water when it is not moving so they may pass over your bath thinking that it is too deep. (this may sound silly to us, but it is true). I get 2-3 times more birdbath activity now. You still have to clean your water and I remove the Wiggler before winter. The batteries last many months. Honestly, the price is a little steep for what it is, but it is worth it for what it does - attracts more birds. It should last many seasons with proper care.
