The six-cup plastic jar is break-resistant and has a lid with a removable measuring cap. An all-metal drive system ensures added durability.
Customer Review: I hate this blender!
bought this blender years ago and I hardly use it.You can't pour out of it without spilling,water gets in between the two layers and it takes forever to dry and then it leaves a dirty film,doesn't lock onto the base, so you have to stand there and watch it or hold it on. Can't find a replacement jar so I'm stuck with it till it quits working. VERY BAD PRODUCT.
Customer Review: you get what you pay for...i guess
When it comes to my kitchen, I always make sure to invest in high quality appliances that will do their job and last a long time. The purchase of this blender, however, is an exception. The blender is plastic and not glass. Originally I thought that it did not matter, but the plastic quickly gets hazy. And by quickly I mean after using it twice. The blender does not lock onto the base, but rather sits there which is quite annoying. I also have a little bit of problem with leakage from the bottom which could be entirely my fault. As a blender, it functions well. But if I could go back in time and buy a slightly pricier blender, I would.
