Query: Good product for smaller bird baths

This is a good product for smaller bird baths. It's 15F and there's a 12" circle unfrozen in the 18-24" scalloped batch (inside/outside dimensions).It replaced another great product - theFarm Innovators C-50 Bird Bath De-Icer- that after 15 years started tripping the GFCI. they'll all do this after a long spell.We replaced with this product as my wife thought it less industrial looking than the C-50. That and we figured we didn't need the 150W of the C-50 for our smaller bird bath.She also painted it. You can also paint the C-50 but it'll still look industrial.So unless you live in South Dakota (my birth place :) ) or have a very large bird bath you'll probably be happy with this product. Otherwise get the C-50 - it's a great product as well for colder/larger.
