I got mad trying to fc a 4.9 star cus it was so easy but i kept shit missing on the same exact slider. Then i threw my pen at the wall and it unscrewed on the tip, and the compartment where the battery goes in. I thought no big deal unitil i noticed the battery compartement wouldnt screw in and that the part where the pen nib is supposed to go in is crooked. So i tried to bend it back lightly and then ripped it off from the pen by accident. Now i have to buy a new huion tablet yay ^.^
