Even though the jar was the correct replacement for my blender the screw down attachment to connect the jar to the gasket and blade would not tighten down correctly and when I thought I had it screwed down tight the jar leaked. I changed the gasket as well and even that didn't work. I gave the product 5 stars not for the jar itself but for the customer service. I entered a return request on the AMAZON site. The company contacted me the same day as the request and offered either a refund or they would send me another one. They did not request I send the other one back. The new one didn't work either and sent both back although it cost me as much to sent them back as the price of the jar. I gave up on replacing the jar and bought a new blender.
