I would refrain from buying a simple product, because they usually don't last too long, and the cheapest products are very poor, especially under heavy use. The fact that a device in a YT video can crush ice is not the same as a blender that is specifically advertised for this purpose. One of the best devices, but for anything but a horror device, is available from Xiaomi, the Smart Blender can not only crush ice, but is also specially designed to do so for a long time.
