I just got this little chopper and let me tell you it's amazing! I have chopped up cucumbers, peppers, onions, cookies, nuts. It's so easy to use. Just pull the handle and those little blades whirl very quickly. One pull gives you a thicker chop, but if you pull 2 or 3 times, it becomes finer. No electric is needed. When you pull the handle, it is not hard to pull. I don't put a whole onion in, but rather quarters of onions. You can even make baby food in this. I would highly recommend this product! It's easy to clean up, just don't immerse the lid.
