After having a Bosch wall oven for a little over three years, I was faced with five service calls and five different replacement parts which never fixed anything.  I finally said no more! I purchased this Cosmo wall oven to replace the Bosch. I am so happy with this purchase! The oven is easy to use and installation was pretty straight forward. As a chef, I need reliability and this Cosmo wall oven is perfect for my needs. Kudos!
