Hm...I'm not sure what the brown is. Biju, if you can send me some pictures thru PM that'd be great. It might just be nothing too much to worry about, but I'd like to see it anyways.

nfpgasmask, good to hear they're working for you. If you experience the same problems as Biju, feel free to let me know. I don't want this to be of a big concern to other buyers. Thanks

Cheers!
