Don't know about Vitamix, but I'm looking into getting a Blendtec. They specifically state that the refurbished ones get a NEW (though it might be blemished) Jar and Blade, so I doubt whether there's an issue. Also a refurbished Blendtec carries a 7 year warranty (a new one carries an 8 year warranty).
While on the topic, anyone has any constructive feedback on high end blenders (Vitamix or Blendtec)?
I ended up getting a Blendtec from Costco in 2017 and used extensively. Last week while make a smoothie the container burst. I needed a replacement ASAP and Home Depot had 30% off on some Blendtec Models/colors. I ordered online with free delivery, but really wanted something sooner, as quite a few household members start their day with a smoothie.
I was in Costco on Friday, and they had a Vitamix in stock but no Blendtec, so I decided to give it a try.
Here are my first impressions about the differences.
Vitamix can make a larger volume. Despite the Blendtec having a larger container 90oz vs 64oz, the Blendtec is only supposed to be filled about half way. That's a major point in favor of the Vitamix for our family (the one I bought in Costco came with two single serve cups, which are totally useless for us. Just cost more for something we don't need).
Vitamix container and cover seem to have better noise isolation, but the motor is definitely louder.
Blendtec has automatic programs which are nice when they work. Need to be careful or else an air bubble can form in a thick smoothie making the blades spin and do nothing. Blendtec has a variable speed dial, and while you can also go variable with the Blendtec, I find the dial a more natural control than the + and - buttons on the Blendtec.
That's it for my first impressions after 3 days with the Vitamix following 3.5 years with the Blendtec.
BTW, despite both having long warranties, I would always rather buy in Costco and return there than dealing with the manufacturer. Though the drawback might be that the replacement item is substantially different.
