I just had my Vitamix A2300 for about 3 weeks now and so far, so good. All the smoothies, dressings, and pancake mixes I have made have turned out good. I love how it chops ice into a smooth blend. I am however getting frustrated with making large portions, since it's just me and my husband! I can't wait for the smaller container size to be available. I haven't made my nut butter yet, but I hope it turns out just as good. That would make the price worth it!

**Warning: it is very loud! I know I read reviews and heard that it's loud, but it's not until you have the actual blender that you realize just how loud it is. Also, my machine shakes when it's at level 7+ (is this supposed to happen?). 

Cleaning is very easy. I haven't had any problems with this. In fact, the square bottom makes it easy to wipe around the blade.
