The left side of my LCD-1s stopped working less than a year after I bought them. So I sent to off for repair and got a reply saying that they didn't have the part and had no idea when the part would be shipped to them.

I followed up every 4 weeks or so and go the same response - so ended up emailing their main customer support centre. They finally authorised them to send me a refurbished set.

So, the issue was resolved in the end (and my pair had also developed a crack, so it was nice to get a replacement) - just took a bit of hassle.
