Northern Industrial Double Auger Mortar Mixer, Model# 21200031
mortar mixer is strong, but needs tweaks
The speed control dial breaks right away. That's ok, you don't need it, it's just a dimmer switch so it doesn't give you any extra power anyway. Keep the machine on the lower gear ratio and you're good to go. Nice strong motor, no issues with torque.
The issue with this machine: the augers spin in the WRONG DIRECTION, or at least they did on mine. You want them to screw themselves DOWN into the mixing bucket, not push themselves out. You can't just switch the paddles because the collets are threaded in opposite directions.
Rather than chop and re-weld the mixing paddles, I took the whole thing apart and switched the shafts- they are identical except for the threads in the collets (probably why it was screwed up in the first place). Now it works great. If yours arrives like this, now you know what you need to do, but if you don't need the thing right away it's probably best just to send the thing back and get a new one. The price point for this machine is low enough that it was worth the trouble, but hopefully this issue is fixed soon.

The mixer is a good value. While the dual paddle mixers that cost $800+ are the best, for the price, this has great performance. The mixer starts soft and you can adjust the speed on the go. I would buy again, and would only buy the fancy ones if I had to use it every day all day.

Mixing a 80lb bag of concrete in a 5gallon bucket can be a challenge but even with bareing down on the mixer it still kept going. A little smelly but it sounds like others found the same thing when under a heavy load. Have yet to see if the direction of the augers can ne reversed. It would really help. Overall I'm pleased with it and a great price!

So far I am very happy with the purchase. If this holds up as others have indicated, I would buy again. This mixer is strong and I am impressed... should have bought this sooner! Now let it last for years!

Awesome for the price.
I am a fence contractor and have used this paddle mixer to mix concrete for several years now.
It has plenty of power to mix up two 80 pound bags of pre-mix in a wheelbarrow, and even to mix it as thick and dry as you can possibly make it. I have even used it quite a bit with added 3/4-1 inch gravel and it never seems to be a problem.
In my opinion unless you are constantly mixing much over a yard this mixer will do it about as easy and fast as a towed mixer while being far more portable and cost effective, and if you are mixing much over a yard regularly consider calling a truck..heh.
I am on my third mixer now. The first one broke a gear after mixing 100s of 80# bags and the second one which had lasted even longer was stolen.
At this machines price point I can recommend it to almost anyone that needs to mix stuff, even if infrequently, and it has proven durable enough to be worked hard and more than pays for it's self when it does wear out.

Works very well much better than the big angle drill I was using and it cost less than the drill

I was kinda hesitant on buying the item because it just didn't look like it had the power to do the job but i was wrong it work fantastically and im very happy.

Good for the Price
First all, finding a twin auger mixer is next to impossible. There not many on the market. Secondly, this thing mixes twice as fast as any single agitator. The end product is better mixed in the same amoutn of mixing time. So for those two points, this thing is great.
I agree about the earlier comment about the ribbons on the agitators being sharp. I would suggest using a file on these right out of the box.
The other thing was the variable speed adjustment. It only lasted for about 3 runs, and no longer works. The motor just turns on and off--Which is my main reason for giving this thing a 4 star rating.
But otherwise, it mixes and mixes well, which is what we needed!
