I own several other food and bottle warmers (3 to be exact) and I love this one the most because of the ease of use. No water needed!! It still has the same effectiveness of other bottle warmers. The time and temperature maintenance are also the same. Same functions and all. But I don't have to keep refilling or cleaning the water out. Faster prep time is better. Less maintenance is better. I am a clean freak so this product was made for me.
