One week ago I sent my MK3 Combro together with a cheque for £7.50 back to Robin Hewitt for repair.
This morning I received it back updated with a new MK4 board and my cheque returned uncashed. It even cost Robin £1.80 return post.

I have heard good things regarding Combro and Robin before and all I can say is
what a tremendous service this company provides. Without doubt they put some other air-gun company's to shame.
