Thank you for your feedback and evaluation, your support are our most precious wealth, and in the future, we will continue to make high-quality products and provide better services.

We apologize for the unpleasant shopping experience, but there is no problem with our product. We provided photos for your inspection before shipping, and the packaging was in good condition. We also shipped on time. When you received the product and raised concerns, we, including our engineers, were actively looking for the issue. It is possible that the problem was caused by a damaged handle on your instrument, which prevented the working head from being used properly, but you did not cooperate with our requests and stopped contacting us.
