Pros: You get a first hand look at how tadpoles DIE
Cons: After your tadpoles DIE,you have to explain why to your sad child!!!
We purchased this kit for our 9 yr old son for Christmas. After waiting nearly 2 months for the Tadpoles to arrive (2 of them for a whopping $13.99 I might add) they both promptly died. Now I KNOW that my son didn't do something wrong because I walked him through the instruction manual step by step. We did everything correctly. After calling the company we were promised replacements to be sent out. We waited another month and now our 4th tadpole is floating upside down, barely breathing.
This kit simply doesn't work! I'm not sure if it's the design or the shipping that causes the tadpoles to croak before they even get a chance at being a "Frog".
NOT RECOMENDED, unless you like having to explain why their pet died to a dissapointed child.
