Can't help I am afraid, every toaster I have had has been rubbish, and only toasted half so I have to put it back in again upside down, the one I have now is better than the rest but it still has to be done, it will however do bagels and crumpets,  I only ever buy cheapish ones as they don't last long, false economy I think as you usually get what you pay for.  But I do have a tight husband who will only pay bare minimum for anything then wonder why it breaks after 5 minutes.
