really not nice. My chondroitin was not available. And it is working so well for me. So I called the factory and they send it to me immediately. What an excellent service. I thank the lady on the phone a thousand times. I am not used to that kind of service any more. I really appreciated it! I called my mother to tell her and she was also pleasantly surprised by this kind of service. She told it to her friends and they immediately ordered it as well. I was ahppy to do something small back to those very friendly people. Life can be sweet.
