I have been trying to start to implement at work that "if you cant do it send to someone who can" which is easy for a company to say I guess. But we have cables that someone took the end off, or lights that need some lube on. not MAJOR fixes but its still time and effort to fix.
Units like yours, is it worth it? In the time you have fixed them all. would you have used them a few times ? would a week fixing mean that you get a year more? half ? Importantly are they missed ? We have some old dimmers and PDU that need breakers fixing, but its been a year, we have lasted without them? Sure. Those 5 stands that need new wedges and feet that have been workshopped for 4 years ? its a few 100 in parts and labour but we never run out of stands.
