I have had the MH-721 since August of 2009. I have had nothing but problem after problem with this thing. It will not finish a cut. I have used Signblazer, Flexi-8, Signcut, and CoCut. I have even Used the USB and the Serial Port. Still Nothing.
I have even went through the process of having the motherboard replaced and still does not work. Still have not got my refund for that item yet. Yes just so everyone knows if they have to send you a part you pay for it in full then they give you a refund, so they say. I was trying to make a simple cut today and the first time it would not cut at all. The second time the set up light just blinked really fast. The third time it cut about 10 inches the reset light, Offline light, and setup light came on and nothing. I have wasted over 40 feet of material today alone.
It would be my best suggestion that you do not waste your time or money with US Cutter. Save your money buy a Roland or something else from another company, not US Cutter..
Ok here is the update from Levi. (10/30/2009 @ 7:55pm est) They want me to pay for shipping of the whole unit back to them and be with out my cutter for over a week for them to try an repair the unit. I have already spent $40 on next day air charges to get the first mother board. Then I had to spend $10 on shipping to get the old one back to them. Plus the $80 deposit I have not go back yet. Cutter still does not work after 3 months and $100's of material wasted, pissed of customers watching me flip out will the cutter not working. A complete and total waste of time, money, and patients.
They say one year warranty, but trust me that will suck you dry in the process. With the combination of the lost jobs, wasted material, lost customers, shipping charges, time wasted. I have could have bought a Roland or other cutter and not had the issues. You get what you pay for, never again will I buy a no named brand item, lesson learned the hard way and expensive way.
I have read where many of you have had good luck with these cutter and I am glad you have not had to go through what I have been in the past three months. I really think US CUTTER should suck it up and send me a new cutter, not a repaired one. I did not pay for a repaired cutter, I paid for a NEW one. I am sue this post will get deleted but hopefully someone will see it and not have to go though what I have been though.
