PiBurn Grip 2 Reliability Reviews:
From Jennifer:
⭐⭐⭐⭐⭐
The Grip2 is a game changer! I went from a 40oz tumbler and forgot to change my focal distance. That would have been game over for me on any other rotary! I simply stopped the job, started it over, and it restarted EXACTLY where it was supposed to. No slippage. So what would have been a ruined tumbler was saved by this tool! I LOVE IT!!

PiBurn Grip 2 for Wedding & Special Events:
From Richard:
⭐⭐⭐⭐⭐
PiBurn Grip that I've had for several years still earning its keep. I found a niche, wedding invitations on wine bottles. The Haotian 10w UV coupled with the Grip getting it done. Hustle hustle hustle.

Overall Customer Satisfaction:
⭐⭐⭐⭐⭐
I just have to say, this Grip 2 rotary is the F****ing (flipping) best. Even with something simple, like moving the fingers up, since I was moving them anyway I flipped the orange brackets around so they protrude out for an even hold instead of lengthening the silver backing plates. Looks like you've pretty much thought of everything and I have been super impressed with the way it just works with everything you throw at it.
For the 10th time….well done

Absolutely loving my PiBurn Grip 2!! I now look forward to getting YETI engraving orders!! This thing is so well built and just.....works. Flawlessly.
Such a good investment.

Frequently Asked Questions from Customer Reviews:

Yes - one business engraved over 200 YETI and other tumblers in 2 weeks without a single issue. Another customer processes 9 bottles in about 21 minutes with perfect alignment.
What unusual items can the PiBurn Grip 2 handle?
