Longer RAY5 New Upgrade Laser Engraver, Laser Cutter 40W Output Power, Engraving Speed Up to 24,000 mm/min, 3.5” Color Touch Screen, App Offline Control, DIY Engraver Tool for Metal/Glass/Wood

Great item great customer service, just know if you want to upgrade the firmware, contact longer.com first with the model number first, do not just pick the one on longer website. This model is not listed there, however they will direct you to the correct one. Item very easy to setup and use and again GREAT customer service from longer.com

I LOVE IT!!!

Fantastic extension kit! I love my machine and now I can do over twice the size of engraving or cutting area. East to put together and seems very strong. Fast shipping ND

This was a huge help in creating larger projects. My only regret is that I didn't get it sooner.

Great build quality, makes doing lager projects a breeze especially when you create panels for an even larger effect as compared to the original chassis. Highly recommend

Works Great! The accuracy is pin point and the extension size is so worth it

This would’ve gotten 5 stars had I not been dealing with the “flame protection” error that causes you to restart the machine 50 times to make it work. Sometimes it works perfectly (I also have the 850x850 extension kit), sometimes it don’t. Longer “customer support” is an absolute joke. I have yet to hear from anyone and the assembly instructions are less to be desired. And I’m VERY mechanically inclined. I’d say spend the extra cash for a different brand honestly. Save yourself some headache.

Muy buena la extensión
