I write my name on the bottom of all my machines.
They happen to be plastic, so I use a permanent marker.
For metal machines, you could use a dull needle to scratch your name somewhere on the bottom.
I also wrote my name on the side of my ott light, so it can easily be seen, to prevent mixups in classes.
There should be no reason that your machine could be switched at repairs although I have seen or heard of it happening but all machines have serial numbers on them. All good shops will note the serial number of your machine on the repair ticket when you drop it off. More likely you may have taken it to someone who says they can fix all machine brands and models and may not be certified to repair or fix your machine. I always ask the repair tech this question "are you certified to repair this machine?" If they respond with anything other than yes I am certified I run not walk out with my machine.
