These are great toasters. I've had my 4-slice toaster for over 12 years. It's £199.95 at John Lewis, and £172 at Amazon (note its the NewGen model, with 2 dials), so less than £120 at Costco is a bargain. It has extra wide 28 mm slots. Here's the JLP info.. Designed for heavy duty use, this tough NewGen toaster has a complete 5 year guarantee exclusive to John Lewis. It can generate toast at a rate of up to 130 slices per hour, as well as waffles, bagels and tea cakes.
Not only can you select the number of slots in operation – useful for saving electricity – you can also switch between bagel/tea cake and defrost settings. You can even buy an optional sandwich cage to further extend its range, and there’s an adjustable foot to prevent this unit wobbling on your worktop.
Finally, each of these Dualit toasters is assembled by hand: you can find the assembler's individual mark on the base plate.
