This is the BEST designed beam combiner on the market. It is EASY to install perfectly on center of laser beam, EASY to center red dot on combiner lens, super EASY to adjust red dot on center of mirrors. Once bolted and powered up, I had a red dot thru a 2mm nozzle hole in 30 secs. Only wish red dot had plug for dc power, but easy to add your own. Highly recommended.
