My Clear tank CNC with Wings got some small cracks at the lower thread area after only few weeks of use. (app. 8 to 10 times opened and slowly and carefully closed for rewicking.)
Still no leaking, but if they grow it can't take very long anymore.
Has anybody else also had this problem, and Is this a case of guarantee or do I have to reorder (incl. 14€ postage from Spain)?
AND how can I prevent a new tank from cracking again after several weeks?
