NinjaSF301 Speedy cooker is a
pretty nifty kitchen tool to have. This comes with a very thorough instructions booklet. There is an App you can install to help you with new recipes. There is a preheat cycle that starts first, then your food cooking timer starts. 
It’s compact so it’s not like having some huge item taking up space in your counter., but still has quite the capacity still. All the parts are teflon-like coated and hand washing easy. It’s nice you can open the lid off and on to check on the food progress, it pauses the timer but it continues once the lid is shut again.
We’re still exploring all the possibilities of what we will cook between rice,potatoes,veggies and meat meals.
Have used this for the 5 days I’ve had this and looking forward to getting creative with new dinners to create. A wonderful Ninja addition in our household.
