I did not find any reviews on Amazon for this particular model 12MS30 that suppose to support upto 12 sheets and 30 minutes continuous runtime. I just received this unit and my expectation were high from this name brand spending 200 dollars on something that amazon basic provides for half the price. Overall I am sitll unsure if i will be keeping this unit but for now these are my main 3 concerns. 1st The unit came in open packaging as if it was previously used. 2nd it is very noisy nothing close to some of the other brands so don't expect it to be low on noise level (as advertised), 3rd it starts to struggle if placing more than 6 documents at a time you can literally hear as if it going to quit any second.
Unless i received a defective model I would advise others to keep these concerns in mind before making a purchase, after all its almost 200 dollars that you going to spend assuming its best in the market.
