This was a superb addition for my hobby work with plastic models. I thought it was defective at first because it is completely silent when turned on. I quickly realized that it was working perfectly. Makes excellent cuts in ABS plastic for model building.

No doubt you are thrown by the price, I can tell you this is worth it but .... you are still not sure. This thing cuts resin, pla, lexan, plastics, acrylics virtually all softer but rigid composites. It has changed my life and it is worth every penny.

I do a lot of Resin printing so this tool works amazing... Sadly, every so often it squills like a siren, and it's hard to get it out of that trance. My earplugs barely even work. After using it for 3 months on the weekends I felt like I could leave an honest review. This does a fantastic job. If you can get by the screaming of the tool ever so often you'll be good. The rest of your household may hate you though

This unit cut paper but little else. Bought to remove supports on 3d resin prints but knife blade scarcely scratched the surfaces. Not recommended

Initial Review: This item worked for exactly 3 minutes before it died in a puff of smoke. From the point it was plugged in until it did not work anymore was just 3 minutes. It was used on a failed model from the printer for a bit of practice, but less than 15 seconds after starting the practice, it died. Update: Phrozen was back to me within 24 hours of posting the initial review. They were very good about getting the information needed, and now a month after the initial review we have a well tested unit that is working well. This one came FedEx and obviously had been opened and tested before sending. The handle and system on the outside are well built and solid, it is comfortable to the hand, and does it's job well. In an average week our printers go through 6-8 kg of Phrozen 4k resin, and the knife lets us cut magnet holes and other changes to our models. If it were not for the initial unit failing we would give this a 5 star review, which is what the resin gets. Hopefully Phrozen has worked out the quality issue and you can enjoy this items as much as we do. Thank you Phrozen customer service, you are one of the best teams we have dealt with, thank you for standing behind your product and making things right.

While not a cheap tool it does really make removing supports from resin 3d prints much easier.

I am an avid 3D printer and modeler, and kept hearing great things about this ultrasonic knife. I took the plunge, and I wish I had returned it while I still could. My experience has been quite underwhelming. If you're expecting to slice through plastic supports like a light saber, look elsewhere. It does cut, but it is slow and requires a steady hand, even for thin FDM material. I have yet to encounter an instance when using my trusty sprue cutters wouldn't have yielded the same result (often faster). To make matters worse, the on button (which you need to keep pressed to activate the knife) is terribly unergonomic and makes the whole operation more difficult than it should. To top it off, the entire unit feels cheap- light plastic, finicky button, it feels like a cheap remote. Again, it works, slowly and uncomfortably, but it is absolutely not worth the price of entry.
