Rated 3 out of 5 by from good jar This is a good jar (the 4-side jar), I bought it to replace an older one that had many miniscule scratches in it and now stains easily. I will still keep the old as a back up, but it's nice to have a new, clean-looking jar again. The jar performs great, and I like the new lid (with easy access port), but I would REALLY like the option of buying either a stainless steel jar or a glass jar from Blendtec. If you guys at Blendtec ever get a glass or stainless steel option, I'll definitely buy one!

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 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 Liked old lid better I had to get a replacement blender jar as the old one started to leak after 600 uses. When i got the new jar, i noticed the lid is not completely closed and it comes apart in two pieces. This is harder to clean this way. The jar handle also is not solid its hollow so stuff can get stuck on inside of it. Im noticing the blades just are not fully blending frozen bananas in smoothies n i have to pulse it a few times after the cycle is done.

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 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.

We have a blended classic 570. I Don't like it as I can't mix a small amt like 8ozs. What small jar do you have that would work and what is the cost?

Asked by: Little mom
Our Twister jar is great for making smaller batches: It sells for $119.95 on our site.

Our ICB3 model is a commercial blender, so you will need to purchase a commercial jar. You can call 800.748.5400 for assistance with placing an order.
