Wet Blade Assembly 104675 STM102R 1152 for Vitamix Blender 500 4500 5000 5200 5500 6300 E310, Base Blade Replacement for Vita-Mix VM0102 VM0103 VM0104 VM0197, Fits 64oz, 48oz, 32oz Standard Containers

I'm giving it 5 stars across the board, for now, because it works. It fits my Vitamix blender (small original container) and that was the first, most important thing. Now for the detailed analysis:1) The new blades are as dull as a butter knife (if not duller)! The original (on the right), are still pointy sharp and have a noticeable edge to the blades. They also seem slightly thinner and better crafted. However, I'm sure it wouldn't be too difficult to swap the blades, if it became a need.2) As can be seen from the pic, there is a slightly larger gap between the base and the blades, the threaded base is slightly longer (by one twist) and the gear may be slightly longer. However, these two aspects do not seem to affect how it fits in the gear mount on the Vitamix, which is good, as more surface area (seated deeper) would actually be beneficial, providing more traction.The new blades turns smoothly, but stiff, which is expected with new bearings. The old ones are stiff and grindy and... well... shot. :-D When I have the time or need or interest, I may disassemble the old ones and replace the bearings. But getting up and running again was of greater importance.As I use our blender mostly for my morning protein shake, as long as these blades can "take the chill off" (cold protein shake isn't much fun to drink for me; the Vitamix is known for being able to use blade friction to heat stuff up on high speed), then it will be good enough. However, if the dullness of the blades affects this function, that will definitely be a negative in my book.

I bought a Wet Blade Assembly 104675 STM102R 1152 for Vitamix Blender sold by seller 'GENQORN'. The item I received was not machined correctly and damaged the blender pitcher when it was installed. The distance between the top seating surface of the blade assembly and the top-most thread of the blade assembly was about 1 mm too large. The rubber o-ring was also larger, perhaps to try to fill the larger (by ~1 mm) gap. This caused the bottom of the pitcher too much stress when installed, resulting in chipping the rim of the sealing surface of the pitcher. The pitcher now leaks, and I doubt if a new proper blade assembly will work because of the sealing surface of the pitcher being chipped by trying to install this badly made blade assembly. So now I need to buy a whole new pitcher because of the bad replacement part I received.

A perfect fit. Was able to resurrect my old vitamix container.

Costs about 1/3 the genuine Vitamix part, but good quality for the price. Easy to install, bearing is stiff at first but the Vitamix is powerful, so it soon spins well. Blends, chops and liquefieds well. Seems durable, no obvious dulling after 30 uses, including ice cubes every time. No leaks, less noisy than the worn blade and bearings.

We've had it for a couple months now. It fits the blender perfectly and blends just as expected

We purchased this to replace the blade assembly for our Vitamix. It seemed to work ok, except when trying to blend something thick, like a milkshake or smoothy. The cogs seem to slip and not turn correctly. After removing and examining the replacement piece, it's obvious that the cogs are not at all like the original Vitamix part. On the Vitamix, the cogs are triangle shaped. This is not. I'm returning.

It was an easy install

install correctly in my blender

Fit like a glove

He comprado varias veces (con este y otro proveedor) tratando de encontrar la cuchilla de vástago largo. Esta es más corta y no alcanza a encajar (queda flotando).El proveedor nunca respondió mis dudas o me indicó cuál es el modelo que requería.Finalmente fuí a un taller de torno con la cuchilla original, la des-ensablaron, fuí a comprar los baleros, y el taller de torno ensambló la pieza (incluso pedí me afilaran las cuchillas- aunque sabemos que vitamix trabaja por potencia, no con cuchillas afiladas). Estoy muy contento con el resultado. Considero que al menos tendrá unos 3 más más de vida.

its too small for the e310 the threading where it connects to the base is too small to reach and the blade is too small compared to the facotry one.

Mi opinión es que la compré 3 veces y no le queda al vaso y yo le pedía el número que necesitaba y volvían a mandar la misma piesa para otra vez tengan cuidado de mandar lo que yo les pida

Que no es clara la especificación no es para modelo VM0103
