Dishonest company motsumi darts

I just need to warn people to be very careful of motsumi darts. In the beginning their service was good. But the last time I bought darts from them it was a problem. When we dart animals with medicine the darts explode on impact. Wasting extreme expensive medicine and hurting the animal tremendously. We complained to the owner called david about the darts. He promised to reimburse us and send us new darts to test. It never happened. Whenever we querry the new darts there is always another excuse. So people rather pay a bit more and buy other brands. Leave this company out. It is not worth the trouble.
