## Customer Reviews

### ⭐⭐⭐⭐⭐ I was skeptical, but it works great
*by M***Y on June 25, 2024*

Way better than dishing out a ton of money for a laser lens. These work great. Nothing else to say really. They fit in my machine, they work great, and I haven't had any issues with cracking or it getting cloudy. Will definitely buy again.

### ⭐⭐⭐⭐⭐ Much better lens than stock K40
*by C***R on December 17, 2018*

Bought this to replace the stock lens in my K40 laser in addition to the Si mirrors and have been impressed by the results. I have never heard of the company Cloudray but I decided to take a risk since this lens was a bit cheaper than the alternatives (who similarly had names that I have not seen). If this lens is in fact a CVD ZnSe that is advertised, then the value (i paid 20) is quite good. I definitely have significant improvement in cutting/engraving performance over the stock lens and it has held up well so far.I'll go ahead and say that this was a good purchase for my situation - the specs say it is good for up to a 200w laser and considering how big a difference I've seen in my performance it would be interesting to see how true that is.If you're on the fence trying to find a safe lens then I would just go for it - I think most people will be happy with this lens.

### ⭐⭐⭐⭐⭐ Worthwhile purchase!
*by E***N on July 1, 2020*

I purchased this lens to upgrade the stock lens on my K40. After doing a ramp test and setting the z-bed to the proper focal length, the difference is noticeable.I was able to produce a beam of about .3mm even with the stock lens, and the Cloudray lens hit that mark as well. What improved greatly, though, was the consistency of beam width and cutting depth across the entire work area.I can now use the entire workpiece in one run as I no longer experience blurry lines or insufficient cuts in the areas farthest from the home position. I've had a lot less frustration and wasted material since installing this lens.In my opinion this is definitely a worthwhile purchase!Ethan PressmannValued Engraving
