This is the absolute WORST monitor company I have ever dealt with. Absolute worst. I originally emailed them in December of last year asking if they could repair my UM monitors. They replied, 'of course they could.' I sent them in, they received them in January and I'm still waiting.
It's been one thing after another with these guys. First the drivers were bad... then they weren't. It was just a wiring issue. Then it was the sound tubes. Then the sound tubes didn't fix the issues. Then, as it turned out, it WAS the drivers after all. After getting the replacement drivers to them, they tell me the replacement driver has a different filter on it. They were supposed to add an additional filter in order to negate the effects of the incorrect filter. This was supposed to be done two weeks ago... now they are ignoring my emails.
Every correspondence has been met with 2+ weeks with no reply. For example, when they first told me they would test different sound tubes, they gave me a timeline for this. It would be done "next week." Then two additional weeks passed with no update until sending them another email. And they would reply telling me they still hadn't tested the sound tubes.
This has happened several times. They tell me they're going to do something on a certain day, two weeks would go by, I'd send another email and they'd reply they would get around to it in a few days. It usually takes multiple emails over the course of a week or so before anyone replies.
They've had my monitors for FIVE MONTHS and they're ignoring my emails. A monitor repair, regardless of the circumstances, does not take 5 months. Under no circumstances is that acceptable. I get the impressions my monitors are sitting in a box collecting dust.
If you're looking for a monitor company, maybe consider someone else.
