I bought this because I had some items where it seemed like the only good repair option. Binder but I think it's a good product to have on hand. I thought it would have a long shelf life and I would have it on hand for those rare complex projects. I was very disappointed when I read the instructions and found that the Bonding Fluid expires in 12 months. I can't afford to invest more than $30 in a product that won't work in 12 months.
