Very good for Laboratories

I cannot believe how smooth this makes my lotions! I wish I purchased it years ago! And it runs silently. I'm so happy with this piece of equipment and highly recommend it!

Once I was able to assemble the stirrer, the instructions were not so clear if you don’t know the parts by name. I suggest they should included parts pictures in the manual in the future. The unit works well and the amount I paid was fair in terms of value. In my test I used a 3000 ml solution it stir really well at low speed, I settled in at 460 rpm even when the solution went from liquid to a more viscous stage. When I set the machine over 700 rpm I experienced noise (not the machine but the actual mixing of product) due to speed and quantity of the sample. CONS My unit has some deep scratches and stainless rods (both stirrer and the rod holding the unit to the base) are stripped off as of the unit is going to rust or is used. Tighten and loosening the clamp to adjust the unit is hard on your hands.

So it seems to be working OK but there’s absolutely no troubleshooting guide anywhere to be found and the customer service is completely horrible. I’ve been trying to troubleshoot for the last month and they reply after about a week and so far have not been very helpful. So all it appears to be working OK theoretically, The light is flashing red and in the user manual it shows it to be Green. I have been trying to find out about this issue for a month and have yet to get a definitive answer on what’s happening. I feel like the machine seems to be working OK but the company itself Has no customer service.

Nice apparatus, highly recommend for the laboratory use.

Great for sauce or gravy

Looked great, led screen worked as indicated by manual. Wouldnt turn on. Recognizing sometimes one gets sent and the transport messes things up We sent it back same day and reordered. Lets try again.

This is definitely an upgrade over my old overhead mixer, which was less than 150 watts. At 210 watts, this has enough power to mix even epoxies and other thick fluids. They don't include any photos of the back, but the back of the mixer is all solid cast aluminum with built-in heat sinks to dissipate the heat from running. The only reason I rated it 4 stars instead of 5 is...I don't know what the little clamp they include it supposed to do, but it really doesn't do anything. It could use a proper flask / beaker holder. But its certainly not necessary for it to do its job. Overall, I'm very happy with it. It sets up easy, is easy to operate, and has plenty of power.
