I was skeptical to buy this dual wave blender initially as it's like a multitasking machine and I was scared that it may not be able to handle a double job at the same time and may become useless in less than a year. To my surprise, it worked very well from the first day I purchased it in 2012. It makes blending a fun task and while preparing juices, it has a dispensing spout which automatically fills the glasses with the juice without making me to empty the jars. With two blending jars, I am able to prepare juices for both my kids at the same time else with my earlier juicer this task used to be painful as I had to wash the jar to prepare the second milk shake. I only need to peel the fruits and this blender mashes them till the fruit pulp is completely smooth and ready to drink. I don't need to check it and start the product again and again to check if the fruit has been completely blended the pulp or not and I just use the dispensing spout to get the fruit juice and serve it to my kids. I only find it difficult to clean and wash this product as it has the jars as well as the bigger jar which I need to wash manually rather than in a dishwasher. I just had to replace the blades once in these 4 years else it still works perfectly fine.
