Love my new blender! – I had a nutribullet that blew up after 1 month. After extensive research (including looking into buying a vitamix) i purchased the Optimum 9400. I was able to pick it up from the warehouse within days and have used it on a daily basis ever since. I have only used it to make green smoothies so far but it is amazing. No lumps at all. My friend has a vitamix and the quality is identical. As an added bonus it is actually quieter than the vitamix! Would highly recommend to anyone looking for a blender.
