Buyers Beware

Please note that you are checking all your boxes as soon as they arrive. I received two boxes, but when I had to install a new lens, I found that one of the boxes was empty. The second lens works well, but the cost of one lens is too high.

Pros
  • Cutting Tools
Cons
  • Obsolete Model

This lens could not focus anything. Cloudy after a few minutes of use.

This lens looked decent out of the box. I installed it on my 80 watt red/black laser...tried the line test and all I got were very thick lines. I made sure the lens was installed properly, which it was...tried again, same result. Turn the lens over and just remember to try... same result. The lens was junk.

Pros
  • Arts, Crafts and Sewing
Cons
  • Thin

Absolutely terrible.

When I opened the package, it was immediately clear that the lens was clouded. I gave the lens the benefit of the doubt and gave it a try anyway, assuming the lens might be blurry to visible light but would be transparent to IR. I cleaned it and installed it in the laser cutter and lo and behold there was a big muddy burn mark. The photos show the TEN-HIGH lens on the right and my old lens on the left. The haze is NOT due to surface imperfections or poor polishing, and in fact the polishing…

Pros
  • power
Cons
  • high price
