Beware of Erexx Dualtron locking System!!! It is like a scam!

Last ride I felt rod wobble. When I check it today, I foud crack on Erexx locking system and I expect, what will happend. And yes, while tightening it happend (on video I don't use force, if you see, it was cracked before I start). 6 months old. And this was not first problem. As some other users, firts use of this crap I bend quickrelease levers (here is video from one of user    • The Biggest Issue All Dualtron Electr...   ). I wrote to Erexx support and it is poor, after I wrote to them, that I don't have interest for this product, simply stop answering. Latest post was "All is OK, proven through numerous sales." To be fair, main problem is in Dualtron and type of locking system. Erexx only make money based on this poor design, but they do bad work on bad desing. It is like a scam!
