Fast Response -
I'm looking for an alternative supplier so I sent an inquiry to Lily Mao about their company's Tension Pulley. I was surprised to receive a response from her a day after sending the inquiry, which was very prompt. She asked me technical details which she would gladly answer thru email. She's also easy to understand, I would rate her English 7 out of 10.
Although we ended up not working with Hangzhou Ocean Industry Co. Ltd. I would like to praise their customer service and hope to have a good partnership in the future.
