Scratches inside jar
on August 25, 2026

I have got scratches inside blendtec jar after using it for 5 years. It should never get scratches and should be sturdier.
I would recommend this to a friend!
Response from blendtec.comBy Crystal Smith, Customer Service, September 2, 2026
Thank you for sharing your feedback. We understand your concern and can understand why scratches inside the jar would be disappointing after years of use.
The jar material is designed to be durable and food-safe. While the plastic can experience normal wear over time and may show scratches or slight deformation from use, it should not shed particles into your food. Scratches can occur from certain ingredients, such as hard seeds or ice, as well as from cleaning methods and utensils used inside the jar.
I've personally noticed some scratches in a Blendtec jar after several years of regular use, so some cosmetic wear can be expected over time. If you have concerns about the condition of your jar or would like us to take a closer look, please give our Customer Service team a call at 1-800-748-5400, Monday through Friday, from 8:00 AM to 4:00 PM MST. We'd be happy to help.

i am worry about microplastics

I have been a royal customer for 20 +years. I really love the powerful base and multitask functions. However, nowadays, the microplastics in the containers is a big concern for me. No matter how careful we use, the jar is still get scratched by the nature of how the blender function. Are you going to come out with a better solution? I don't want to hear that BPA free jar is save. I don't want to eat plastics at all.
Please work something out. I hate to switch to other blender.

I have never had a bad experience with my blender. I’m actually just looking to get a new jar. Only because mine is old and I just want a new one. I don’t even need a new one.
I would recommend this to a friend!

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!
I would recommend this to a friend!

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.

Jar fail
on November 16, 2024
Posted by: Lorenski

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
No, I would not recommend this to a friend.
