We opted for this larger model after hearing from people that they wished theirs was larger. We Are happy about our decision and are enjoying the ease of use and the fact that we can avoid using our wall oven in the summer. We had a minor issue and contacted Gowise customer service and their representative Talore helped us and solved our minor problem, even though it was not purchased directly from them. Reading customer reviews about the great customer service at Gowise also helped in our decision on buying this brand. Anyone thinking about buying this model should measure their space carefully, as this is a large and requires some air flow space around it. We also highly recommend purchasing disposable liners so clean up is easy.
