Personally i,m getting a little bit tired of this to make it clear to everyone who wants to build a quad but what the hack i will make it clear one more time.
The Aixiz lens is not suitable for using is in a Quad, Dual or Octo combiner.
It will result in a huge combined Fat useless beam!
Kvant, rgb, arctos and others only use quality single lenses instead of the triple lenses so why even try...... They already tested it before coming on the market with their products.
