In all honesty, I am sorry the sale did not work out.
This is an Etha at a bargain price. I'm sure that someone who has spares for it will be able to fix it.
Matt has done the right thing and offered a refund. He also sent the gun via recorded & insured delivery, which was again the correct thing to do.
Also, others have stepped up to the plate and offered to refund me.
I can't ask for much more than that.
As soon as I receive the refund, I will send the gun back to Matt, recorded & insured.
