Hello! I received the products two days ago.
After use, I found that the device operated abnormally, unlike the ones I had used before.

I got a painful tingling sensation when the laser beam struck my skin. The hand trigger would fail at times to make connection with the coolant holder even when it was in use.
For the above reasons, I would like to return the product and get my refund accordingly.
