Indeed. the problem with a lot of smaller equipment is that it can be sadly not very good at its job--I have had a number of underpowered microwaves, etc., over the years.
I feel "Microwave" should be on the list above. I use mine to... reheat tea and leftovers and steam veggies.
Went for years without one and didn't miss it much. It does mean instant gratification leftovers, though, rather than having to reheat in the oven--but reheating in the oven tastes better.
