Regrettably not the best toaster. 
Bad points are.
 It only has one temp for all 4. So doing 2 sets of different bread types at the same time doesn’t work well  ie toast on one side and crumpets on the other.
Warburtons bread does not fit in this toaster on its side. Which would indicate the slots are narrower than cheaper models. 

If all you toast are all the same slices of small bread then this will be ok. Other than that if you like a mix or have a busy house. I would look else where  I won’t keep this for long and will buy a new one when possible.
