I'm interested in purchasing an electric wax pen. I've been
researching the Kerr Ultra Waxer and am impressed with it. I've come
across similar models made by Renfert. They market their products for
dentistry, but I'm wondering if any of you have used any Renfert
models. If you can offer any or details about comparison
of Renfert vs. the Kerr Ultra Waxer, I'd greatly appreciate it.
