a girl mention to me that the control ring of her GGTS was tight. If any other person have the same issue he can ask me to send him a new one with 10 euros shipped as my waranty says. No other person told me this but 1 person is enough for me.
I will make some extra rings after 1 month so if anyone has the same issue he can ask me to send him a new one
