### ⭐⭐⭐⭐⭐ Super fast

### ⭐⭐⭐⭐⭐ Updated: New replacement tube works great
*by I***N on November 23, 2022*

Update: after contacting the seller, they promptly sent us a replacement tube, which runs great. Easy installation. Healthy and stable beam. Clean cuts. Happy kids. I hope this tube will have long lifetime ------------------- Purchased the machine in July, and have been using sporadically, once a week or so, for short low-intensity jobs (10% of laser power). Worked great when it was working. However, even with adequate cooling (the coolant temp has always been within the 18-20C range), the laser beam switched to the doughnut-shaped profile in November, i.e. useless for any kind of job due to the inability to focus the beam properly, and now the tube has to be replaced.
