Lasers only worked for numerous months with me answering questions and helping me pick the right equipment. Emails always answered promptly. I would highly recommend doing business with them as they actually stand by their products before and after the sale.
We purchased a 30W fiber laser with Rotary. Shipping was fast and the folks at Lasers Only are great to work with, after sale support has been exceptional! We will use Lasers Only again for our next upgrade.
The rotary tool can be very handy, I however haven't spent enough time to figure out how to fine tune it.
I'm sure that will happen soon.
