I love CJ's work and have bought some small stuff from him but there is nothing wrong in talking about an issue with someone's product if you are sure that it was not due to mis-use / negligence.
If it was indeed a weld quality issue and if CJ acknowledged it, its good for both because the customer get his issue taken care of and the manufacturer gets valuable feedback and a chance to improve their product design/manuf process.
If i was thousands of kms away (like i am usually, in this part of the world) from the manuf. then i would definitely sort it out myself, but would make sure to leave some feedback to the manuf. and other users. If i was close by to the manufacturer and they agreed to replace the item, then i'd be happier.
No need to pile on the OP and call this as "bitching like a little girl".
