FourSide Jar is rated 4.35 out of 5 by 20.
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 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 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 Light weight and Durable I bought this about a month ago and I use it frequently. I couldn't be happier with how well it's built and the way it suits my needs.

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 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.

Will all the recipes that call for wide side work with this jar

Asked by: Pathill3
Yes, all recipes will work in this jar. There may be an occasion where you'll have to cut down the recipe as this one is a little smaller than the WildSide jar.

A little clarification to the answer you gave to Susanne three months back: when you say you need to increase the recipe when using a WildSide jar instead of a four-side jar, do you mean the WildSide doesn't work as well on smaller amounts? 

Asked by: Gail
Correct, the WildSide is a larger jar than the FourSide, and was designed to handle larger batches. It can blend smaller amounts, but it works best if the ingredients cover the blade.

The bearing of Blendtec FourSide Jar leaks. What can I do ?

Asked by: Wang
You will need to contact the place you purchased it from and see what their warranty is. Here are some tips to help prevent this from happening in the future: - Clean your jar immediately after use, don't let food sit in it. - Before each use, turn the blade with your hand from the bottom of the jar by spinning the drive shaft. - If the jar hasn't been used over an extended period of time, you may want to put warm water in it and let it sit for 15 minutes, dump it out and then turn the blade with your hand to ensure it's not stuck.
