Calphalon has issued a recall of their XL 9 Speed Blender. The recall is due to safety concerns with the mixing blade.
The model affected is: 1832449 or ME600BL
More details of this recall can be found on Calphalon’s website. They are also offering a pretty cool free gift to anybody that sends their old blade back in to the company, so that is a pretty good incentive to take part in this if you have one of these models.
