Update to my review:
We promptly received a very helpfull response to our problem and can now make our son happy and excited again. Thank you so much. We will definitely recommend Chai to our friends and family.
We gave the gel pellet machine gun to our son on Christmas day as present. He was so happy and excited and couldn't wait for the gel pallets to grow to size, but unfortunately on Wednesday day (2 days later) the one gear striped and broke now the machine gun is not shooting anymore. This is quite disappointing.
