Laser Engraver Forum

I have never had a lot of luck with my Full Spectrum 5th Gen Hobby Laser. I have replaced some parts and I'm ready to swap out for some good quality mirrors. I know I'm trying to polish a turd, but it's all I've got. Any suggestions for a reliable source would be really appreciated.

The mirrors are 20mm if that helps.

I have to say I'm very disappointed that nobody took the time to respond. I am a little lost on which mirrors to buy and what is a good deal or not.
