Hello all. I have finally used both the BlendTec and VitaMix… and want to give my two cents.
I heard so many good things about BlendTec, and I was in search for a high-speed blender… so I got a BlendTec. Wow, 3 HP! versus 2HP for the VitaMix. I wanted to try. I would agree with many that said the BlendTec is easy to clean – both the container and the base. And, yes it’s powerful enough that you may not need a tamper; but, don’t stuff the container too much or the food will not fall easily and get blended. (I’ve done that… and wanted a tamper) Otherwise, it’s fine; just when you think it won’t blend it all… it does! The VitaMix is a bit trickier to clean out, but the container is bigger to fit that extra liquid and I really like my tamper! This way, I can move the blended food around so I know I have reached the right consistency – like for creamy dressings or no-bake creme pies. The BlendTec allows you to start the blending and you can walk away to do something else and it will stop on its own. Wonderful!!! ...except, you may have to clean up the few drops that came flying out from that tiny hole on the top of the lid. What I like about VitaMix the most (which BlendTec doesn’t have) is that it has that opening on the top to throw in a few more ingredients. You have to open the lid on the BlendTec; I thought maybe you can remove that middle thing on the lid, but I didn’t try too hard. Oh yes, and the other thing I like most about the VitaMix is that it has a longer warranty. The most thing I like about BlendTec (which VitaMix doesn’t have) is that it fits on my countertop under my cabinets.
I dealt with BlendTec customer service because the base was not level and they immediately sent me a replacement. It seems they really can’t fit all that stuff in the base… but, the replacement is stable, you can tell it’s “crammed” in there.
I don’t plan to return the BlendTec for 2 reasons: 1) It is $50 less than the VitaMix and 2) I already have a VitaMix (my in-laws are using it right now).
Both are great blenders. My husband thinks that the BlendTec is not as powerful as the VitaMix… judging only by the amount of sound they make… and a few chunks of food we find more often in our BlendTec blended mixture. Maybe I will blend it longer… but, what’s the point of preset settings if they can’t do the job right the first time. Also, VitaMix has more than twice the warranty that BlendTec has.
I know, it sounds like I prefer VitaMix… but I think I will use the BlendTec more often only because it fits on my counter better in my tiny kitchen. The true test will be when I make my orange creme pie. The chef (of this recipe) said you could only make it in a VitaMix (I think she meant high-speed blender)... so if the BlendTec can do it, I’ll be happier.
