Chen was extremely helpful. My motor broke on a Saturday and I was panicking because that was the only motor that I had. Without that, I can't work. I was calling the BioHorizon rep trying to get a new one but she didn't reply (and she still hasn't replied) I needed the motor urgently. Thank God I found Global Dental Shop on google and they actually had someone live chat with me in a Saturday afternoon!!! The person who chatted with me was Chen and he was gave me the information that I needed. I called on the following Monday and Chen remembered chatting with me and helped me to place an urgent order. He followed through the process to make sure that the warehouse send out my order ASAP and I get the new motor the next day so that I don't have to cancel my patient appointments. I bought some other items from them and Chen gave me discounts on everything I bought! Chen is also very knowledgeable about all the items that I purchased so he was able to answer all my questions! I highly recommend this company! That's how businesses should be!! read more
