I agree with the above posters, I'd like to see a link for clarification of this DannyBen
The link has been removed as it was in the general discussion. But what it said, and first I agree..... there is no need 99.5% of the time to ever have to adjust the center pin as its spring loaded, but.....
The user did adjust the pin. It does have a screw slot there for adjustment. That YiHi themselves acknowledged this and have already started production on a new version that will have a new pin without the screw. They have stopped shipping the old version (but obviously all inventory as of now at dealers is the old version) and will start up shipping the newer version soon.
Furthermore, they have refused to honor his warranty claiming it is user error. The same way as if he opened the device it would void the warranty, by him adjusting the "adjustable spring loaded pin" he too voided his warranty.
YiHi did solder in the Pin and it will snap. Those are the facts and i've since confirmed this with a dealer.
