Good day people, got my X Cube Ultra about 2 weeks now and really enjoyed it until yesterday when i heard this hissing noise from my room and when i checked it was the Ultra on my dresser firing away on it's own and had to do a battery pull to stop it. Now, when i reinstall the batteries it's okay but after the the first hit it just keeps firing, any ideas??? BTW reinstalled the firmware and tried different batteries, so i'm stumped. Any suggestions?
