No Busy LEDs & Buttons
So far, I really love my stove. I purchased it because I wanted a mechanical-only range – no busy LEDs and buttons. In fact, I’m so pleased that it doesn’t have a timer/clock and all those other features that depend on computer parts.
Great looking and straight forward range
We purchased the Cosmo as we like the industrial looks and reputation for quality. Also important to us was the lack of circuit boards, electronics, and touch panels.
Quality Range
We just replaced an old Viking with this stove. So far it’s been working great. Seems very well made and was less than half of the price to replace the Viking. Very simple which means less stuff to break. Highly recommend 👍
The Look
Love the look of the stove. Commercial style yet perfect for home cooking. Can’t wait to bake all my homemade biscuits in the baby!
