My new Four Side Jar is fabulous and a lot quieter then past jars.The new lid has a nice center piece to release steam or add ingredients. Excellent product.
I've had my blendtec blender base since 2021!!! I probably should have replaced the blender jar a few years sooner, just due to discoloration but the jar still performed perfect. I finally replaced it due to the underside of the jar rusting where the blade sits. I've used my blender 981 times!! I love the counter feat, it's so fun to see how long it's held up! I 1000% recommend getting one of these. It may be the last blender you ever need!
