Our Verdict

Breville Die-Cast 4-Slice Smart Toaster

Breville the Eye Q 870 Auto 4 Slice

The Breville the Eye Q 870 Auto 4 Slice and the Breville Die-Cast 4-Slice Smart Toaster are both great options for daily use, but they have different strengths to consider when choosing between them. Go for the Eye Q 870 Auto 4 Slice if you want toast that's more moist and fluffier on the inside after toasting, or if you want an option that leaves fewer crumbs on your counter. Choose the Die-Cast 4-Slice Smart Toaster if your priority is toasting evenness or if you make a lot of bagels, since this model's one-sided toasting mode works more effectively. It's also smaller and much less expensive, so it's a good choice if you're trying to save space or cash.
