This is a fantastic gadget. It works perfectly everytime.
You need to practice a couple of times, and you will get used to the right amount of rice and filling you need to fill each half of the Sushezi. Unlike the sushi mat, the Sushezi produces consistently the same shape and size sushi.
Only snag is that the diameter of the finished product is 1.5 inches. It does NOT make dainty bite-size sushi. It only makes a FULL [man] size sushi. But in spite of this, I am happy to give it a 5-star. Quite sturdy and easy to clean - just soak it in warm water.
BUY it if you like to make your own sushi. You will not regret it.
