I bought a striker 7.5w myself and found i was not impressed with the beam divergence. My first laser i thought more power would go farther so I'm wishing i could trade it for a green 532nm, something that goes far. I got beam expander for it and it doesnt do much good on the 7.5w blue.
Well I'm new here. I ordered a sanwu striker a year ago with no problem and then my last order was in april. I texted them and francis said pretty much the same thing to me about the shanghai lockdown so I'm waiting for my april order as well
