I've been using Ecoflex products for years, but the 00-35 Fast is my new go-to for quick turnaround molds. The viscosity is low enough that I don't always need to vacuum degas, though I still do for critical pieces. It picks up every single detail from my 3D prints. Just make sure your mixing containers are clean because platinum cure can be picky about cure inhibition.

Great value for the money. You get a lot of mileage out of this kit if you're doing smaller molds.

Used to use the OOMOO stuff but this is way better imo. It’s way stretchier and doesn’t tear as easily when I’m demolding tricky shapes. Def recommend.

It's okay. A bit faster than I expected so I had to rush the pour.

The low odor is great, but I found it a bit tricky to mix exactly 1:1. My first batch stayed kind of tacky for a while. It works fine once you get the hang of it, but there's a learning curve for sure if you're used to other brands.

Complete waste of money... it never fully cured and left a sticky mess all over my master sculpt. idk if it was a bad batch or what but i followed the instructions perfectly. Super disappointed considering how much this kit costs.
