I want to commend Cris at Eggtimer for the great products and support he provides. I never would have thought that I would be able to assemble one of his kits, but I’m pretty much 10 for 10. The instructions are so good that even someone like me, with no experience soldering, can be successful. I periodically have to ask Cris for some help, and I’ve broken parts but have yet to dork a board. Cris always comes through for me. I suspect I ask too many questions and need too much help that I’m wearing out my welcome. But he shows no sign of that with his timely, polite responses. So if you’re thinking about an Eggtimer product and wonder if you can be successful, I urge you to give it a try. They are not only great products, but there’s a lot of satisfaction when you power it up and the lights blink right and the beeps beep right.
