I have had switch problems with both my lava tube and now the gripper. Fore some reason with in 2 months both of them are having the same issue.... I hit the button and nothing, it will fire if i push the button either real hard or find the right spot. I am not sure if i am doing something wrong or if this is an issue others are having. I am very gentle with my things and not hard on them (nother have been dropped or mistreated). If these are know issues, is there anyone out there that knows how to repair them, or any recommendations for a decent priced vv mod. Any help would be appreciated.
