I read all the reviews before I bought this product. I simply can't understand the negatives. I've always had a corded immersion blender and it was fabulous. I don't use this to crush ice, but I do use it everyday to make your chia seed pudding with two types of nuts, frozen fruit, almond milk and plain yogurt. I find it very powerful. Is it as powerful as my corded? Cuisinart? No. Is it close? Yes. I make a lot of soups in an instant pot. I don't fine chop anything anymore and I can use this and it climbs up all the vegetables and pork or whatever I put in the soup. To charge lasts for pretty much 7 days. On the 7th or 8th day of using it once a day for about 15-20 seconds, it runs out of batteries and it charges easily. So much nicer than having the plug and a cord every time you want to use one. You can't beat this one for the money
