I've had mine for over a year and have used it every day. I don't use it for main meals unless I can't be bothered cooking. I use it to make the veggie stock concentrate (best thing about having a TM and has saved me a fortune just in store bought stocks!), sauces, nut spreads, dips, curry pastes, smoothies and coconut milk icecream. I also use it every day to grind up chia seeds, walnuts, pepitas, etc to hide in DS's meals or bliss balls.
I also use it to make washing powder which has saved heaps of money.
We started saving $50 - $80 a week when I first bought it. Spending so much more now but switched to all organic but our shopping would be so cheap if it wasn't organic.
The biggest thing for me was that it allowed me to really cook everything from scratch without spending all day in the kitchen. It also allowed us to remove all preservatives and artificial ingredients as well as minimising exposure to chemicals in packaging and the BPA in tins.
My mother bought one and hasn't used it since she got it 6 months ago. She has the same attitude she did when getting a computer for the first time and doesn't know what to do with it. I just know if she just started with anything she'd realise how easy it is and find so many ways of using it and cutting out the junk she eats now as well as saving so much money.
