This is my 2nd replacement jar. This shouldn't happen. The bottom leaks black liquid. Blentec told me it's because of a malfunction in the jar...yet I had to pay for it. This new jar the lid lifts a little when it's turned on. It makes nervous it will completely come off so I feel the need to keep my hand on it.
I had gotten my blender from Amazon not realizing the pitcher would leak immediately! I dealt with it for awhile and then decided it is probably best to replace it. I saw comments all over the internet about how only getting the pitcher direct from Blendtec would fix the problem. I ordered and within the week I had my pitcher!!! NO LEAKS!! Such a great product. Should have just ordered directly to start with!
While the top has slight improvements, the blades tend to be tight & the motor has to push a little harder; but if it stops the blades from seizing because of bad seals it's all good.
My Blendtec is an asset in the kitchen. It eases the work for many recipes and can actually be the only thing used to prepare a meal. I have been recommending it to many.
