Well, I try to plan ahead. Our investment in ADJ/Elation gear is fairly close. You're a bit ahead of me for now.
Knowing that certain seasons see more traffic than others, your military logic doesn't fall into place in the private workforce. It's not quite so simple in the private workforce to get people in, train them up, work them and boot them when times get slower, then repeat the cycle. It makes more sense to keep the existing people in place with the right skills and have them work year-round. Sure, it would be nice to have some seasonal help they can rely on.
When I send in gear for repair, it really depends on what's going on how I behave. For the most part, I have things laid out so I can take the down time for that gear with other jobs(many I do don't need lights, I'm a sound company). So, being without a light for some jobs doesn't make a difference for me.
I will say this: Gear received needs to be checked into the system on the day it is received. Regardless if they can get to it immediately is secondary.
Right now, I have issues with China in general. I have limitations in what I can buy that doesn't involve China, but I'm sick of the substandard workers in China and the substandard work they do. Even so, short term tests for quality control doesn't reveal all problems, because some things can fail just sitting aroudn.
ADJ does better than most. They definately do better than their competition. DOn't even get me started there!
But if you're not happy with ADJ, then it would make good sense to not use their products. I am NOT happy with a competitor of ADJ, and despite the fact I have a fair amount of their gear, I don't and won't get any more of their gear, even if it competes LIKE for LIKE with ADJ at a lower price.
I personally won't deal with a company I don't like. Silly me. I send off a light with a new $20 bulb off for repair, and the company does a crappy job repairing the fixture and loses the light, well, that just plain makes me angry. To have a second fail and also get a crappy repair job, well that really doesn't do anything for me. Not to mention my entire set of 4 of these are known for breaking bulbs. Fortunately, I found a place that sells the same bulbs for like $6 each. I can eat a $6 bulbX4 per show if I have to, but not $20X4. Ouch!
Or what about not shipping me some repair parts because they changed the part and didn't call me to see if I wanted the different part, yet already charged my card? If that's what the new part is, why am I having this conversation? Just ship it, I'm smart, I can figure it out.
Jingles is helping me choose NEW fixtures by either ADJ or Elation to replace the existing non ADJ/Elation fixtures I have.
I've had lots of positive experiences with ADJ. I don't see that changing anytime soon.
