Hi there, if your thinking of making your own cbd oil or vape oli etc I think I can help you in making your decision easier. I've been making cbd oil for just over a year now and I used to use a rice cooker till I came across a video on you tube. I noticed some guy using a Magnetic Stirrer which I've never seen or heard of before. I did some research and came across a website called www.magneticstirrergeneral.com which really helped me in making the best decision for what I was using it for. And trust me when I say using a Magnetic Stirrer over a rice cooker there is no comparison and saves so much time and effort. Hope this helps anyone wanting to go down the same path.
