"would never do business with this company"

company based in China, if anything's wrong you have to send it back to China and it will take months for them to send you a new one and postage to China is very expensive which you have to pay even if the item cost less than the shipping fee.

"Good communication"

Good communication, sent my order of 4 in two separate packages delayed in time, but happy to get my compete order still. The portable dental unit and turbine handpiece is very good, but price is also reasonable! Good deal. good Seller.
