I just finished my blue 6x with the module and lense you are asking about and it works great. My laser can light a match in about 1 second. I havent had time to put it through a bunch of tests but i am happy so far. The module is made of aluminum and has some weight to it. Works good as a heat sink too. There is also an option on the site for a red module as well. They claim a 10% increase over axis. I have attached a pic of my finished laser I spent $20.00 having the head of my host milled out so that the module slid down inside it and it came out sweet.
