Dualit classic toaster. Was replacing Breville and other brand toasters every 18 months or so.
Dualit cost more than twice my previous fancy units. So far, it has lasted 5 years, of nearly twice daily use. All parts repairable or replaceable, but haven’t needed to yet.
I feel like you must be lucky. My parents had a Dualit intending to never need to buy another toaster, but it was so often away being repaired they had to buy a cheap one for the interim. We had 2 Dualits at work and same problem. One of them has been permanently trashed now. They also take SO LONG to toast?!
I got a mid-range Kenwood 4 years ago and it’s going strong.
