First off, I don't build fishing anything, and as a matter of fact, fish typically laugh at me when I do go fishing, but that's beside the point... I build golf clubs. Living in SW Virginia it gets pretty cold in the winter and I have no heat in my shop, aside from portable heaters, so I needed something that would get my 2-part epoxies warmed up enough so they can flow and mix. This bottle warmer is perfect for that. I've had it for about a year and wanted to make sure I gave it plenty of time before I wrote a review. Plain and Simple... plug it in, put your water in, place your bottles, turn the knob to how hot you want the water, go do some other things (for about 15-20 minutes), and when you're ready to assemble, the epoxy is ready to go. This warmer works great for warming epoxy, no matter if you're in the hot or cold! This has been an invaluable tool for me in my shop!
