Blendtec FourSide Jar: 32oz Clear Copolyester Blender Accessory, Hand Wash, 3-Year Warranty

Always a 10 in my book. Wore out my first jar. Replaced.

These jars are great! My old one lasted over 5 years with heavy use. The jar never chipped or cracked though, worn out bearing instead. These jars hold up surprisingly well and don't take on stains or odors. The new jar is performing great so far. Very happy with Blendtec products!

Not sure if it’s the new design of the jar, or that my machine is past its prime (over 400 drinks made), but it is not chopping everything up. I’m constantly left with a chunk or two of frozen banana or strawberry that won’t blend in.

I would like to see a removable, replaceable blade instead of having to purchase a new jar.

I bought a blendtec blender and the jar failed after about a year. I decided to go ahead and buy a whole new blender again because the jars were so expensive. Same thing happened. Now I have 2 bases. Sad

Seems of good quality, sturdy. I hope this one lasts longer than the last one did. For the price you pay for these blenders, the accessories are certainly not cheap.

I’ve been a long time fan of Blendtec. My first blendtec that I bought 15 years ago is amazing. I bought a brand new one and it didn’t work as well. I bought a new jar for my old one and it leaves pieces of frozen banana not completely dissolved. Also leaves small protein powder clumps. Blendtec has changed and it’s such a shame.

Hi quality product, but the lid is too tall for my ABC blender. I need to hold the machine cover down by hand, or use my old jar's lid.

I loved the original jar that came with my Blendtec, but this one is a really poor design. The top blows off if you put chunky items in it like frozen fruit. It makes quite a mess.

Love how the enclosed four sided base helps to lessen how loud it blends.

I loved the new jar and the rubber top is so easy to clean. It is almost like it is non stick. Our old one just wore out. We use ours regularly and no issues. I swear by Blendtec !

These jars and the blendtec bases last forever. I own 2 and the 2nd one still under warranty, when the jar blade gasket gave out it was replaced as promised.

Nice to have a new jar, replacement my 7 year old jar. The bearing had worn out and the jar became too noisy, but it was used almost daily. No complaint, it lasted longer than I expected. Quality materials, sturdy, this FourSide pulverizes anything to a smooth consistency. My only issue is the opening in the lid for this version versus my former lid is too small, difficult to add ingredients and it fits a bit too loose. Ugh!

It is a good item overall. My original jar lasted over 5 years but with infrequent use, like about 30 times a year. The jar started leaking from the bottom and when it was used for the last time, some small plastic particles got mixed up with the food item that I was blending.

I’ve been using Blendtec for years and have gone through a few jars. While I am still not really a fan of the square shape, as it is hard to clean, I do admit that it blends better in that shape compared to the more rounded jars on the market. This jar seems more compact and uses less materials than previous but it also feels more plastic-y and cheap. Does it get the job done? Yes. Do I love it? Meh. Glass would have been better, as it doesn’t stain over time. But this thing is built to be replaced in 1-2 years, which seems to be a larger trend, so it’s hard to be excited about it.

I love my Blentex! I bought mine 20 years ago! I love the new lid on the jar! It totally protects against overflow!

We shall see. The original jar lasted 527 uses in less than three years. My wife uses this just about every day to make a smoothie to take to work. I used it during chemo treatments to help with calories. I wish this jar could be repaired. The top needs sealed by the bottom should be able to be serviced. The bearings went out on the original. Get some bearings for American Roller Bearing Company.

My jar bearing is broken AGAIN. I bought a replacement jar at a local dealer to replace the one that originally came with my blender and broke after only a few years. Now this one is 3 years old and the bearing is sticking and won't blend correctly and making the motor run strangely AGAIN. I'm so angry.

First one broke!. Today is the best day ever and I told you that.

I bought a replacement jar for my blender and within the first few washes the jar is discolored making it look dirty.
