Larger models and different makes are available from Argos, Comet, B&M etc
I bought it for a disabled relative (think dyspraxia, tremor etc) to try and give them a sense of independence to make their own lunch occasionally. I still need to assist for whisking the eggs, chopping the fillings etc, but the sense of achievement it has given them is great.
Ideal for an individual serving, 2 med eggs is the maximum to use or it's too full. Also fillings need to be small.
I also bought a set of mini silicon spatulas to use with it to accommodate the disability and have decanted olive oil into a small glass jar and add it with a disposable pipette.
It's very easy to clean, ignore the 5 minutes in the name, you switch it on, wait til it heats up then cook for as long as you want it done, then switch off and let it cool before cleaning.
It could also be a handy gadget for a child to learn how to make omelette without the hazards of normal cooking, although the interior plates do get hot, so care is still needed.
