Should be coming into the country soon. I will be testing them out on my snakes this season so i can have some data available about them. 100% hatch rates have been achieved consistently with them. The hatchlings absorb the yolk more efficiently and they seem to have shorter incubation times. Dont know what the price would be yet, but they are very affordable. A larger version is also in the works. Of course there are some that would say they can make these at home. But i highly doubt it would be as good as these. They are dishwasher safe too. The little rails on the grid are adjustable for most eggs and can be removed. The big eggs are the size of chicken eggs. The container gets placed in an incubator. They would also be ideal to keep young green pythons in as well as hatchlings that have to undergo their first shed.
