Rated 3 out of 5 by from Grinding sugar into powder I love the blend! Just wish you had a feature that I could use to help me grind my sugar into powder. It does a fantastic job except now the container leaks causing the plastic on the bottom around the impeller melted. Due to the friction in the grinding process because the sugar is so hot when grinding. Is there a container that can help me grind my sugar? It's one of the key ingredients in my chocolate business. Please help me. I only had the blender for few years maybe 2 years and just start my business a year and I already need a new container.

Rated 2 out of 5 by from I got a replacement because my jar was leaking The new one maker so much noise that I am sure there is something wrong with it I would appreciate if you send me another one Besides I don't think I should have been charged for the replacement since that problem is a flaw in the design I like the blender but it is becoming a problem

Rated 5 out of 5 by from Perfect smoothie maker! We received our much anticipated Four Side jar a few days ago, and have used it nearly every day to make smoothies. It works nearly flawlessly, and I say nearly only because if you add too much frozen and solid ingredients, it will fail to blend without tamping down the mixture. This has only happened twice, however, and with a quick tamp, a perfectly blended concoction emerged!! Love this blender, an this Four Side jar!!

Rated 5 out of 5 by from Love the Four Side Jar! I bought my Blendtec with the Wildside Jar on sale at Costco last year and, while I have loved the operation of the blender, sturdiness and ease of cleaning, the bigger jar wasn't designated for some of the recipes and smaller amounts I wanted to use. Since getting the Four Side jar, I find I use it all the time with all the recipes I want!

Rated 4 out of 5 by from Improved from original I have had this replacement for over 4 months and it is performing well. I like the improved top with the larger pop out which allows for stirring. I think the gasket issue needs to be work on more, but no issues with that as yet.

Rated 4 out of 5 by from "We hope you'll write about your FourSide Jar while it's still fresh on your mind." Actually its fresh on our minds daily, since that's how we use it. Would prefer it be made of glass...
