Review on Comtim Silicone Reusable Expandable Universal by Amber Loridon

Pros: Fits in many jars, Easy to put on and take off, Pretty cute with legs and tail, Easy to clean Cons: I use 3/4 3 ounce can and 1/6 5.5 ounce can for morning and night feeding. I assumed (!) that I could uninstall it, take something out and reinstall. First use was great, fit snug and held up. Easy removal to access the next aliquot. BUT: There was absolutely no way for me to put this thing back in the jar. I probably could if I had six arms but then it would slip off as it didn't have a suction/air seal. I was ready to send them back when I decided to wash them. No problem. Works like the 1st time. So you need to wash it after every use. Save less plastic sheeting going to landfill, but use more drinking water just to (unnecessarily) wash it. So I guess you choose your poison. I'm sticking with these but really want them to work without rinsing after each opening.
