This stuff is fantastic! It's my first time using silicone to make molds, but the Ecoflex-30 was so easy to use, I had no problems with any of the molds. The silicone picked up every detail. I wasn't concerned about bubbles (no vacumm or pressure was used), but to my surprise there were very little if any in most of the molds. Those that did have bubbles, they were tiny and certainly did not affect the quality of the mold at all. Mixing was easy, but be sure to make sure to stir each original container before each use (this is mentioned in the directions and on the containers). I used separate cut solo cups for each part (A + B) to measure, stir again and then mix into one. The working time was easily 20 minutes (prob much longer). I did add some unused left overs into a mold after about 45min-1hr and there was no indication/issue in the final mold. All gell'd together nicely. I'm impatient, so I usually pulled the molds at 4 hours (in a 65F degree room) and they looked great. If I weren't so impatient, I'd probably let them go another couple hours - Some recommend a full 12 hours to be safe. The silicone is very stretchy, but also very strong. I tested one that I stretched to easily 4x its size, and it held up great. I've only had the stuff for about 2 months, but the silicone mixtures are still good (used some today). I'm not sure of the shelf time, but the container does warn that it has a short shelf life. Will definitely order more.

This is the softest rubber I've ever worked with. I like that it's clear. It's firm yet very stretchy which makes it super easy to demold. I've purchased this item twice.
