Query: Crappy piece of plastic

I have no doubt in my mind this product would have worked fine BUT the first time I adjusted the gain on the converter, the small dial broke off! The gain dial wasn't under any kind of "extreme pressure." It just broke off way too easily which showed me just how pathetic the construction is on these things.I ended up going back to my original choice for LOC's>>[...]This other LOC doesn't look as pretty but is much more durable and trustworthy in terms of construction. Save yourself the frustration I went thru and just buy this other LOC instead.Cheers
