Tbh, I don't find the turned stick ones any better than a spoon or a flat spatula. They can actually be a bit uncomfortable to use all the while the porridge is coming to the boil. I use the flat one my Dad made though and it is really good. It stops the porridge sticking to the bottom and it gets right into the corner to scrape out there too, and it's not tiring to use.
Each to their own though.
Toddy.....who made porridge every single day that way for years on end
but see now ? rolled oats are great in the microwave
So is the meal that needs soaked first, though it takes a bit of stop/let it rest/start again, for best results.
