### ⭐⭐⭐⭐⭐ Great Product Fast Delivery
*by J***E on September 25, 2024*

Was literally burning through lenses left and right. Contacted manufacturer and they pointed me towards this lens. Such a difference in quality and performance when you have the right lens! If you have a CO2 Laser, this is the focal lens you need!My machine manufacturer wouldn't list the specs for replacement lenses because they want to sell to you after market parts. (Not mentioning names, but rhymes with Jonport. Due to other quality issues with this machine I vowed to NEVER spend another dime with that company. So I needed an outside source for replacement parts)Thanks!
