Tried all three mixes as instructed and was very disappointed. I've been using Bondic for years and it works exactly as advertised. I even put the sample under a 10 watt 244 diode UV array and after an hour it was still not fully cured. The light they provide looks good but does not come with batteries and is very dim compared to the KEY LIGHT that comes with Bondic. As a control, I used some LCD-T resin ($30/liter) for my SLA 3D printer, and it made a much better adhesive than that horribly smelly junk.
