My ol' lady was sayin' that our two birdbafs, one a typical wide bowl on a pedestal, the other also a wide bowl, but resting in a thick styrofoam thing that rests on the ground, often freeze virtually clear. We're in the upper Midwest US, and it gets damn cold. I've got heaters in the water, but on occasion the GFCI trips and it freezes over. Bummer for the birds, squirrels and other lil critters that depend on it. I've seen as many as twelve squirrels at the birdseed and water in winter, but in summer rarely as many as eight. I'm guessin' that they depend on our food and water, so we try to ensure it's always there for 'em. Our cats watch from the two big windows overlooking the yard. Anywho, I digress. So, the birdbafs freeze on occasion. That's why I got a rubber duck for each one. That way, if the duck's moving in the breeze, it must be unfrozen. We tried three different ducks. The first two floated, but not that well. One took on water over a week, finally settling to the bottom. The other floated very well, but far from level/duckish. So, I ordered two of these ducks. These things float perfectly. They're well made, and look very duckish. They bob and blow around with even a gentle wind, thus perfectly solving our problem. Not only that, several of our neighbors have told us how much they liked the ducks. So, if you need a good rubber ducky, this is the best one I've found. Inexpensive, seems to be made of good plastic, and floats very nicely. I'll update this review 'round this time next year, after carefully looking at our ducks to see if coloration changes as a result of a year of sun exposure. In the meantime, since you're readin' my review, you know you want a duck, right? Just do it, get your duck(s), be happy! BTB, I gave this a four-star review only because I save that fifth star for things that are extra/surprisingly good, high-quality stuff, or the seller treated us very right. For me/us, four stars is excellent, good stuff. Five stars, amazingly good stuff. Sadly, one of our ducks was found floating with its head under water. No, it's not the duck's fault. We have two birdbafs in the yard, one atop a traditional pedestal and one that sets low, near the ground so the lil critters and backyard bandits can use it. Well, the duck in that one apparently so annoyed one of our guest critters that the duck got bitten a couple of times. So, it took on water, and after a while it just couldn't float well. Again, not the seller's fault, or the maker of the duck. Our other one is still in great shape, bobbing along with the breezes in the birdbaf. So, might be good to avoid putting one in a low water feature, so it doesn't so annoy your visiting critters that they bite it. Getting two more today, one to replace the dead one and the other for a friend's lil kid, to float in the baf. Have a super(rubber) ducky day, y'all!
