Review on Liquimo Hourglass Management by YoYa Toys by Brian Stepp

I like this product very much. My grandkids love watching the colors fall and when they combine to make other colors. They like to compete between three units to see which one is empty first! I want to raise two points about these Liquid Motion toys. 1. Two units have multiple exit points, making one color finish faster than the other. I don't know if this is intended for that or if it means they are buggy.2. The base should be wider. I think adding an extra "hem" or "edge" of clear acrylic on each end (maybe just 1/8" or 1/4" wider) would make them sturdier. I find that they tip over very easily, increasing the risk of breakage.
