    My first time buying from here, and I have a feeling that it is going to be great. hopefully the ptm7950 does the job, I will surely be buying more stuff from here and referring people if it does.

    It was not clear how to choose the color of the cables. I needed to improvise. It would be great if you offered intermediate lengths of cables too. 25 cm, 15 cm,
