Vitamix Personal Cup Adapter - 61724, Clear

Just got it and had to try it out because some of the other reviews made me nervous! I made sure the rubber seal was dry and properly placed, placed ingredients in order per directions (frozen fruit, leafy greens, liquids). I had no leaking issues and did not notice that it was any louder than the normal blender attachment. Everything seemed well blended, no chunks of greens or frozen fruit, it actually seemed more well blended than the normal blender. Cup holds just the right amount for me, very happy with this purchase so far!

Although my Vitamix blender can make a great smoothie, these smaller containers and adapter make it easy to make a one serving size to go. Love the versatility of these and clean up is fairly easy. Be aware that it is only compatible with certain Vitamix models, so read the description before purchasing for your unit.

I first started out by reading a bunch of reviews. I was reluctant to make the purchase because of all the comments about leakage. I also didn’t realize they make two different model's. I had to dig out an older model blender I had for this model to work. But at the end of the day it was well worth it. I wanted to address everyone’s leakage issue. Most likely because you don’t have it screwed on right or tight plus like me you want to overfill it. I find if I make it tight enough and I hold my hand on the top while it’s blending. I don’t have any problems with leakage at all. The funny thing is the first time I used it. I didn’t have it timed enough, and it leaked really bad and went flying everywhere. It was quite comical.I feel like the cup kind of comes loose when the blender starts blending and that’s what causes the leakage but if I hold it in place with my hand, I don’t have that issue at all. And to me it’s well worth doing that rather than trying to use a big container to blend one drink. If I had to do it all over again, I would still make my purchase. However, I wish I could find the model that fits with my newer blender. But everyone knows it has been discontinued and so they wanna charge you an arm and leg for them. I’m just sorry that they discontinued them because I feel like the issues with these attachment is user errors. Because I did it myself the first time I used this one.

I actually bought this kit so I could try using the Ascent Series blending bowls on it, even though they are listed as not compatible. Some reviewers stated they worked and some stated they did not. I can tell you, along with the provided pictures, you can make them work, but it's not an ideal setup.The design of this adapter seems odd, with what looks like a container being attached to the adapter, of which you actually install the blending cups into while it's upside-down. It took me a while to figure out why they did this. I believe it was for safety. If they did not have the outer container on the adapter then you could potentially install the adapter on the base and run it without a cup being installed!... or if the cup somehow came loose it could be very dangerous. That is my best guess as to why the outer container was added to the adapter base. In addition, the Ascent series cups and bowls have magnetic strips installed at the connection point to signal that a cup or bowl is installed to a digital type base, in this way they can prevent the base from running if there is no cup or bowl installed. Of course my old 5200 series does not have any sort of safety mechanism to prevent this.What is not ideal?1. It is awkward to install the cups on the adapter with the outer container part there, but not too bad. If you use the Ascent bowls it is much more awkward because the bowls are so much shorter and down in the container, making them hard to install and remove, especially if you have large hands.2. As others have stated, the shape of the cups narrows so large chunks of material can get jammed high up in the cup and not get blended.3. Cleaning the adapter is difficult because the blade and dirty areas are in tight proximity to the outer container housing that is part of the adapter. You also cannot just dump soapy water in there and run the blender, because the adapters container housing has holes at the base to drain out, ie it does not hold liquid in itself, nor does it have a lid anyway.4. I suspect some people will have issues with this setup leaking. It would not be hard to get food material between the rubber seal on the adapter and the cup/bowl mating surfaces, thus likely causing a leak. In fact, if you install a cup or bowl to blend and then remove it from the adapter and then place the adapter right side up again, it's almost certain food contaminate will drip onto that mating seal surface, so if a cup or bowl is reinstalled without first cleaning it's likely to leak. I also found I had to use a lot of force to tighten the cups/bowls so they would not leak. A lot of pressure is created inside the cup/bowls when blending, not to mention expansion due to the heat being generated inside the cups/bowls. I have very strong hands and arms and the force needed to install and remove the cups/bowls from the adapter such that they would not leak was quite tight and difficult to remove afterward. People without as much strength might find it difficult to get it tight enough to stop leaking... and/or then find it very hard to remove the cups/bowls from the adapter.5. As with most Vitamix stuff, it's quite expensive! I got these things on good sales and it was $130 for the adapter and bowls. I could have bought a "Tribest Personal Blender PB-250", or similar, for half the price without a lot of the above mentioned issues.For myself, I like the high quality Vitamix build and materials, and not having multiple blenders for slightly different purposes, so it's still worth it for me, but that's a personal choice.
