Although the delivery took some time,the machine is satisfactory,feels good and easy to operate.

Thank you for such a good product that helped me a lot. The customer service was very patient. Thank you very much

I have used the machine once and I like it very much. The use process is very smooth and the communication with the seller is very pleasant

After checking the instructions, the machine works well, and this is a foot-switch controlled picosecond.
