Replace the counters

It’s quite a job changing the lazer counters. Just take your time and be careful.

Great! Back up and running

Old laser counters finally stopped. These got me back up and running at 100%. Easy to swap out.

Worked great.

The online video showing how to replace the sensors is very well done. I was able to follow it and get the new pair installed in my classic version of the sensor with no problems. Great service. Great price on these sensors. Thanks!

Useful replacement

My unit had progressively failed over the past several years. Blasting with air and suction withe vacuum eventually failed.
Ordered replacement counters and they work perfectly. Fairly easy to install given the instructional video.
