I wish I had been as lucky. This is for the Muse Hobby Laser.  I have nothing but problems since I bought it in April.  The power supply had to be repaired twice which means it cost me to send it to them both times. I have been busy getting my studio together and have not had time to devote to running lots of jobs. I would get the machine up and running, make sure it works and then continue working on the other things.  When I come back to the machine some time later, I find I have another issue.  I worked around them, now I can't.  I've spent more time trying to work out issues than have it do actual work. I am not a dunce when it comes to handling these kinds of things. I've printed less than ten jobs on it.  It does all sorts of strange things which I didn't want to call in because I didn't want to spend more money to send the unit to them. After RE3 2.0 got installed I can't use it at all.  Can't get access to RE3.  I've done factory resets, connected directly with ethernet to my PC, changed out cables, tried other computers.  When it works you could use Raspberry Pi to run it. (Can't do that now either.)  One time it wouldn't work on Chrome or Firefox or Microsoft Edge but then it started working on Edge and executing a file unexpectedly.  Sometimes the Muse screen comes up, sometimes it doesn't.  When it does come up it's actions are not always the same.  It does odd things. The behavior is not consistent.  I have ruled out firewall issues, ethernet cable damage and everything else I can think of. When RE3 2.0 got loaded I now no longer can use the machine at all.  I sent in a message for support Friday night but won't be able to talk to them till Monday.  I thank God I have not committed anything related to work on it yet.  All I want is my money back. I spent a lot more money to have this unit over a Chinese version because I didn't want to have the issues. I feel I would have been better off buying the less expensive Chinese unit and get through its issues. Get outside of the warranty period and the thousands I spent will be gone. The unit I have is a lemon and I think I'm going to be screwed after the warranty period. I don't want to put any additional money into this.  I'm ready to take my losses but I don't want to lose all my money.  They get better than one star because they have tried to help me and went above a beyond this last time but I also demanded it.  I suspect these guys don't like to hear me coming because I am one frustrated and angry customer.  I feel like I've been suckered.11/22/2019Update - Got the control stack back.  It worked the first time I turned on the machine.  Then it no longer worked.  It told me to contact support, which I did.  Watched the videos made changes, double, triple checked connections.  Now, while I don't get irregular behavior I get a consistent message telling me to shut down wait some moments then restart.  It the problem continues contact support.  I can not rely on this for business use.  I noticed that at least one reviewer said about having a positive experience.  I am glad for him but it does not make my comments not true.  I am requesting a refund.  I will see how they respond.  How much money will I lose?  I will post an update of how they end up handling this situation.
