Let me start by saying this resin is a dream come true for anyone printing flexible or shock-absorbent parts. I've used it to create custom gaskets, phone cases, and even replacement tires for small machinery - and it performs brilliantly in all these applications.

The 80A Shore hardness hits that sweet spot between flexibility and durability. Printed parts can bend and twist repeatedly without cracking - something I tested extensively with a printed wallet prototype that's survived months of daily use. The tear resistance is impressive too; I accidentally dropped a printed seal from my workbench and it bounced rather than shattered.

Print quality is excellent right out of the bottle. Details come out crisp, though like other translucent resins, you might need minor adjustments to eliminate artifacts (I found increasing exposure time by 0.3 seconds worked wonders). The surface finish is beautifully smooth - so much so that I've stopped painting some decorative prints.

What really surprised me was the minimal odor compared to other flexible resins I've tried. The water-washable feature is a nice bonus too, making cleanup much easier. Just remember to wear gloves - this stuff sticks to skin like nothing else!

The only real downside? Price. At nearly $50 per kg, it's an investment. But considering how far 1000g goes (I got about 25 phone cases from one bottle), the durability makes it worthwhile for functional prints.

Pro tip: That anti-spill insert in the bottle? Genius. I've repurposed mine for storing mixed leftover resins without mess.

Bottom line: If you need tough, flexible prints that can take real-world abuse, this resin delivers where others fall short. Just be prepared to tweak your settings slightly for optimal results.
