This toaster does indeed come with a 12-month guarantee with ourselves.
#2 Does it toast the bread slice on both sides or just on one side?
This toaster will toast both sides of the bread, creating great-tasting toast.
#3 Does this toaster take long slices like warburtons bread, does it take crumpets
I use Kingsmill which is 12 cm by 14 cm for a slice and the toaster can toast this either long ways or short ways.It is wide enough for crumpets. I did have to buy some wooden toast tongs from Lakeland to remove the hot crumpet though.
