Our Verdict

Dualit Design Series 4 Slice

Breville the Eye Q 870 Auto 4 Slice

The Breville the Eye Q 870 Auto 4 Slice offers better overall performance than the Dualit Design Series 4 Slice, but both models have strengths to consider, so your choice will depend on your priorities. Pick the Breville if you want more evenly toasted baked goods or a toaster that leaves fewer crumbs on your counter. Go for the Dualit if you want a toaster that works faster or if you toast a lot of bagels, since it's better at toasting only one side. It's also more compact, so it's ideal if you need lots of capacity in a smaller space.
