Our neighbour also have a Thermomix and they really enjoy it as it is simple to use and don’t take a lot of space in the kitchen. Their step by step recipe on the screen is clearly an advantage and the product had a lot of different recipe. Later in my life I would consider to buy one 
If it is too expensive, you can look at the “Monsieur Cuisine from Lidl”, way cheaper, but maybe lack of quality ?
