They're engineered for restaurants so they're absolute overkill for any home use. Your home toaster isn't going to successfully pump out 400 slices of toast per hour.
They're engineered for home use, that's why they are sold at home depot, on amazon, and in retail outlets.
Restaurants buy proper commercial gear, from hospitality supply depots. You don't buy restaurant ovens, and gear, from amazon or home depot. A strong tell is, restaurants aren't looking for candy red, enamel coated stuff. They want stainless, and their gear is hidden away in the kitchen, and they don't want to pay a penny more for trend.
Honestly, why would you say that? There is nothing about this that is commercial.
A 30 yr parts warranty is what tells people it's actually well engineered.
Searching for "Dualit toaster" on Amazon brings up their classic line as the first result. While available in a range of colours both the four and six slice versions are advertised as "Built for commercial use." https://www.dualit.com/products/original-toasters
My aunt had the six slice version rated for 240 slices an hour when she ran a bed and breakfast. I've also seen the four slice one in smaller cafes. All in the polished stainless steel finish of course.
