| Customer Reviews: Average Rating:  Rating : - It Takes a Gorilla Grip to Prevent Leaks If you take the time to wade through all of them, you will find dozens of reviews that complain about leaks, along with many more that claim they have experienced no leaks. This disparity results from the amount of strength it takes to tighten the blade assembly to the jar. The amount of torque required to get a water tight seal is beyond that of anyone with less than average strength. The latest revision (the 600XL/A model) comes with a special wrench to assist in removing blade assembly. You might also use it to tighten the assembly, but Breville recommends against it because it migh result in overtightening. I'm amazed that the Breville engineers have not been able to solve this problem. They obviously recognize it as they changed the design in the latest revision (600XL/A) but it still takes a gorilla grip. The worst of it is that any leaks will drain into the base which houses the motor and electronics. No wonder they only offer a one year guarantee. + See Full Customer Review |  |
