I used it as well, not something you want in your tank since it doesn't have the greatest design and eggshells and eggs themselves will find their way into the tank, and very few shrimp will find their way into the tank.
I eventually ended up doing a little experiment with a 3g Eclipse from Marineland that I had laying around. I used a small 25w heater to keep it at the recommended temperature (78-80 I think?) and a few airstones from a small pump with an in-line air control to keep the water moving a bit and keep the water oxygenated. Worked pretty good minus the fact that getting the hatched shells out was a pain.
