Workshop Heaven are great but I bought a Quangsheng #5 from them and it had a pretty huge manufacturing problem. The mouth wasn’t square and the paint inside it had been scratched off. I think the machine used to mill the mouth was out of square. I returned it and got a refund (including shipping) but was put off by the experience (put off the plane manufacturer – not WSH!). Glad yours is working out for you though Ken!
