Let me start by saying this resin is *wildly* underrated for functional prints. After testing it on gaskets, phone cases, and even a tiny tire for an antique sewing machine part, I'm convinced it's one of the most versatile flexible resins out there. That Shore 80A hardness? Perfect sweet spot between squishy and structural.

The magic happens when you bend a printed piece - it springs back like TPU but with way crisper details. Printed a Gridfinity tray that survived my chaotic workshop drops, and the surface finish? Smoother than most 'standard' resins despite being flexible. Though heads up - supports leave slightly more noticeable marks due to translucency.

Major win: cleanup is shockingly easy for a tough resin. Water-washable (unlike most flex resins!) with minimal odor. That anti-spill bottle insert? Genius move - I've repurposed mine for mixing leftovers. Downsides? Price stings a bit, and dialing in exposure needs patience (add 0.5-1s vs regular resins).

Where it shines: functional parts needing both flex and precision. Think watch straps that don't snap at buckle holes or shock-absorbing drone mounts. Not ideal for ultra-fine miniatures though - that rubbery quality makes support removal trickier on delicate bits.

Pro tip: Shake aggressively before use! My first print failed until I realized the pigments settle more than usual. Once dialed in? Consistently perfect layers without the brittleness plague of cheaper 'ABS-like' resins.
