I love this addition to our Blentec set. It is perfect for 2 Smoothies or 2 Rum Drinks. It blends well and cleans well. My only issue is that I received in the set 3 Plastic Disposable Cups with 3 Plastic Lids with 3 Plastic Straws. In this day and age of 'No Plastic', I was a little surprised to have this automatically added to the box. People can use re-usable cups and, if they need a straw, then a metal or paper one. Hopefully Blendtec can take these out of the package and give other suggestions. Besides that I love it.
The GO is my favorite Blendtec jar. I love being able to make and drink my smoothie in one jar and I love the convenience of being able to take my drink with me on outings. I also like being able to take off the blade section, clean it and set it to dry while still using the rest of the jar. I've used my GO about a dozen times and every time my smoothie has been entirely blended and smooth. Most times I have put frozen berries and greens into the jar with some water before heading to bed. In the morning I simply add any other ingredients such as powder and sometimes ground nuts.
This works fine, with the exception of adding powders. Doing the smoothies in the order that you are supposed to add the ingredients… the powders seem to stay on the edge and not fully mix.
