I held out against one for ages but succumbed when I saw one at a bargain price. I now use it a lot during winter months.
reasons are
easy prep, I use frozen onions, butternut squash, sweet potato,spinach, ginger, garlic plus easy to prep fresh veg like carrots and potato so prep takes seconds.
walk away, switch on and go and do other things, come back and the soup is ready and still hot, no stirring, no burning, I feel like Max in The Wild Things.
small footprint for storage.
only disadvantage, it doesn’t go in the dishwasher and I hate washing up by hand, even though it only takes seconds.
