getting a mychron serviced?


I have a mychron 3 that seems to not want to work fully, tried re-setting it, new batteries, same thing... It will work just fine for 5-10 secs, then just shuts off... is there anyone who repairs/ works on these besides AIM? If not, will it cost me more to send it in than it's worth getting repaired? Trying to figure out if I should just toss it vs repairing it

Thanks, Matt
I'll buy it..Mychron has excellent service..had the stud come loose from the rear of my mychron 4 and touch the board..fried everything..they fixed it for free and paid the return shipping..
