His 3.1W AX unit for $179 shipped is a deal.
Iv'e yet myself to purchase one but I only have 2 laser's over 5W that have been metered and don't plan on anymore.
In time though this AX would be perfect for my needs..
Hi, I agree with the guys here that laserbee is the best LPM producer here . I have 4 of his LPM's and others. If you are looking for a 20W LPM he won't have one his top LPM's are 10W. Sanwu is sending a LPM to review and they state its capable of handling 20W's . So when I receive it I will put it up against a Laserbee 10W LPM to see how close the reading are of the two units.
