I had to replace the blade unit and got the heavy duty blade unit. The teeth on this new unit were immediately chewed up by the base motor unit. The company replaced the unit free of charge and the second time I used it both the teeth on the base motor unit and the blade unit disintegrated. I was told that I need to replace both when the base unit is back in stock. It is too bad this unit does not last more than a couple times. When it works, it is great. But hard to justify spending money replacing a product that is of defective design.

I bought many sets of magic bullet blenders over the past 15+ years. I would say its quality has gotten worse and worse. After 4~5 months of light use, it not only made big noises, but also leaked some black tar looking liquids into food which is really a health concern (you don't realize it until you blend some light color food). Totally lost trust on this brand and switched to another brand.

This is a must have for the kitchen. It is so quick and convenient to use for smoothies, bulletproof coffee, pancake batter, etc. Looking forward to using it to make frozen margaritas this summer. Super pleased with my Magic Bullet purchase. Would definitely recommend.

We got the bullet as a wedding present and one of the little white tabs broke then today (8 months later all the rubber came off of the bottom of the blade and now we can't use the machine at all. I am a little disappointed in the poor quality of this machine.

The second time I used the new Bullet to blend a protein shake (all liquid) the rubber drive gear on the underside of the blade that engages the drive motor impeller completely fractured. Shortly there after a second one broke doing the same thing.Obviously a product defect. When it worked it worked great, but the only "Magic" about the Bullet is if it works. This is another product based on a great idea that is built so cheaply it does not last long enough to justify the purchase price. I definitely would not recommend. Just buy a regular blender; I have one the we received as a wedding present 50 years ago and it still works.

I bought this last year for college since I had to start "The Virgin Diet." I was really excited not to have to lug around a huge blender and the package clearly stated it could make smoothies. So I finally got to using it this month and the first day it took me over an hour (this is giving the bullet a break after 40 seconds of on usage because it cannot run for longer than a minute at a time) after this time, my fruit was still not chopped up. I had to eat my acai bowl with hard frozen fruit in it. I tried to make a smoothie next with only 1/4 a cup of frozen fruit...still frozen fruit does not chop up. I left my frozen fruit out for 2 hours while I ran hoping that may be the problem, still, my fruit does not chop up. I had the NINJA at home and truly wish I had spent the extra money on that then this awful thing. I can't do anything with it, it's just as loud as a blender, and the results are just basically what you started with with a little mush here and there. Extremely upset over this product.

I am on my 3rd Bullet. Not because of the motor failing but due to the failure of the blades. They wear out and then leak. I use my bullet daily and I am happy with the results. But the failure of the blades due to friction causes wear and then leakage into the motor. Against the instructions advice I cleaned it under the sink and it got very wet. Let it dry and still works. I had 2 more motors/bases so had nothing to lose. I am waiting for replacement blades to come in and I hope they work. They have a limited life and will not last forever. I am trying to keep them lubed with olive oil now to see if they will extend their life. I have noticed the cups are starting to crack and haze and some of the "ears" on the cups have broken off. I would consider this normal wear. I do however see the blade wear as excessive and a point failure. I not even sure if a replacement blade will fix the issue since it may have increased the size of the hole in the base as it wore out. And as I said I use mine daily. I find the flat blade excellent for grinding nuts into a paste suitable for a nut butter. And so much easier to clean then a large blender. If you are good knowing you will be replacing the blades and possibly the black base occasionally or buying a new one then I recommend this product. Note: My use may be excessive, I use mine bullet maybe 3 times a day everyday. And the motor is like a tank, that, I'd rate easily a 5/5.

I bought this last year October 2019 and already broke. The coupling on the base of the motor got destroyed and destroyed the coupling on the blade part. This is the second bullet I buy. The first one had the same issue. I thought it was an isolated event but it seems these items cannot handle frozen fuits. Both items were used solely for the making of fruit smoothies. I am disappointed and will not be purchasing any of these items again. It is a waste of money.

I've been using this blender for about a year now. My family enjoys making smoothies of many varieties, and I'd say we use it several times a week at least. It does a good job of blending ice and items used to mix with it (fruit, nut butters, milk, ice cream, etc.). I will say that when blending ice the blender is extremely loud. We usually have to walk into the next room because we can't hear each other talking in the kitchen. The consistency and flavor turn out pretty well. I've also used the flat blade for blending spices and coffee beans (only when my burr grinder wasn't working). It worked fine for that as well. Recently I've noticed that the blender has been leaking under the quad rotor blade assembly. I have repeatedly seen liquid in the base of the motor portion of the blender, and I'm worried that this will lead to damage or bad smells (or both). I've checked the seals and all of that, and even made sure that the blade is securely tightened to the cup. The leakage is coming from under the blade and into the motor cavity. It's still working, but I don't think I would buy this one again. It's worked for me so far, and it wasn't terribly expensive. However the noise and quality would lead me elsewhere.

I've had my magic bullet awhile when I got a good deal on it.. I've just now begun making smoothies every morning with it.. I've been using fresh fruit that I've frozen (doesn't get as rock hard as store bought frozen fruit).. Mix yogurt, carrot juice, powders.. Yesterday my magic bullet starts making some weird noises so I remove it. The blade spins using a rubberized grip that sits into a hard plastic turner.. The turner completely ate up the rubber.... Lucky yesterday I found my spare blade.. Go to work with my smoothie.. This morning, same thing!! The blade didn't even make it to finish one smoothie.. Now I'm going to have to just jump back into my ninja since I know that works.. Only plus to the magic bullet was the perfect cup to go.. OH and now I have this weird white powder from the rubber all over my kitchen that I have to clean up for the second time!!
