we have used our blendtec wildside blender every single day since we got it, twice a day. blends really, really, really well. hearing protection is only necessary for the sensitive earred folks. usually i have to hit the smoothie button twice for a really smooth green smoothie, but it always turns out great! i haven't ventured past green smoothies, but the recipe book that comes with it is really extensive, with soooo many great sounding recipes. i did a Ton of research before i made this purchase. totally pleased. we have only had it 5 days, but we love it!
