I bought this about a month ago and have never been happier.
My wife is 7 months pregnant and we wanted to be sure she took advantage of all nutrients that our food had to offer. We blend green smoothies at least 2 times a day and are pleased with the break down of all the ingredients when blended. Our previous blender would not completely blend the ingredients, particularly the green as it would leave chunks.
Now we are confident that everything we blend becomes bio-available to my wife and the baby.
The only thing negative I might say is that towards the 50th use we received an OVERLOAD/OVERTEMP error message. We shut down and let the machine rest and cool down as per the troubleshooting instructions provided in the manual. Unfortunately this continued on to the next day. Before calling into customer service we let the machine cool for another half hour or so. The issue never came up again, hopefully never again. Thus the 4 stars.
been using for about two months now and i love it! Powerful, easy to clean but would be so nice to add a feature similar to the vitamix wand, i have to stop and mix the contents frequently (depending on what your making). Looks like i will have to invest in buying the twister jar. I've also noticed that it doesnt blend so well in small quantities, everything gets pushed below the blade and it is inconvenient when i just need a small batch. Other than that i couldnt be happier with this product!
My husband researched blenders extensively prior to this purchase. We actually had to return our first blender; but upon exchange, which went smoothly, our current blender (same models) has been perfect. The first use of our first purchase resulted in melted corners of the jar and base where they contact. Upon receipt of our new blender we realized how much louder the first blender was than our current. We had no point of reference for noise with this being our first Blendtec purchase and demos were in Costco, a loud open warehouse. I expect noise...it's a blender! We just didn't know how much.
