## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Lots of bubbles
  

*by X***  on Reviewed in the United States on 4 January 2024*

I have done a ton of research into this product and it felt like it was the perfect one for my project. I am making some very small parts so maybe that's the problem? Either way the parts are very brittle and there's so many bubbles that it makes it useless. I have tried both in a vacuum chamber and on it's own. Product is very easy to work with and it has a good working time which is nice, maybe larger projects will function better.
