I've had the Classic 575 for a couple months. Its a great blender. I use it for protein shakes which contain cashew milk, protein powder, spinach, banana, chia seeds and ice. The only thing is if you use just a little too much ice it sounds like the ice is stuck but it really isn't, its just too thick and causes a pocket to form. I've also used it to rice cauliflower. It is very loud but powerful. No sharp blades. Has a cleaning cycle that makes the clean up easier. Overall its a great blender.
