I've only had this for two months, but my husband and I use it every day (morning and night). We stuff it full and it blends everything smooth as can be (exactly what we needed since we're using it to help get our veggies in!). I guess the one thing that "surprised" me is how it has a slight rubber smell once it's been used on high and that when really full and on high it will move around unless held - but honestly, so far so good, and absolutely smoothness! Haha. My thoughts - if it stays like this for even just 2 years it's SO worth it (though a hefty price, health is so important!)
