I bought this to replace a 10+ year old electric Bosch convection that had died. (bought it used for a couple hundred and lasted more than 10 years) so more than got my monies worth! We rarely used convection on are old oven but now it is all we use for nearly everything on this new oven. Not many ovens in the 27" width to consider. However, we have had this for 2 years and love it!! We looked at the more expensive models but after really considering what we usually use are oven to do we decided on this one. We are extreamely happy with how it works and how quickly it heats compared to the old one. Will buy another Bosch oven again in the future!
