Absolutely love it. Works great with the Mauster 3s I got.

Bought as a Christmas gift for my husband, he loves it and it works very well! Very fine and precise details. Very impressed!

No matter the setting it will not cut 3 mm nasswood

This is the laser that came on my XE Pro unit for about $600.00.The lens cracked after about a years use of normal use. I've done about 50 to 70 small projects, always kept in under 80% power. Now a replacement will cost me almost 3 quarters of the total cost. I should have went with a different brand. Notice how they no longer sell the XE Pro engraver, or about any others? Just the replacement lasers. No way would I buy another Foxalien laser of any kind. I even bought the roller for round projects, but it sits sealed in its box because of the cracked lens. Sorry Foxalien. No way could I have used this if I wanted to engrave on a constant basis.

It says it's a 40 watt laser which is actually input power although it says output power. The true output power is the same as the optical output power which is 10 watts. Dont buy this thinking that you're going to get 40 watts of cutting power because you're not...you're getting 10 watts of cutting power, 1/4 of what they want you to think you're getting. Always compare optical output power when checking out lasers because other brands may say 40w and actually only have 7.5 or as low as 5watts of optical output power and you're trying to figure out why this new laser doesn't cut as good as the one it replaced. Always check optical output power wattage and don't be fooled by less than honest advertisement.
