Just wanted to throw my experience in the ring here. I sent out a pair of TF10s to be reshelled way back in April. It did take a while...longer than most, but after talking with Adam, whom I may add is a very straight forward person and never once told me anything but the truth, I found out he was having issues with the silicone process. After giving him the OK to proceed in acrylic, he had them back to me promptly. I never had any issues actually calling and speaking to him, then again I am rather patient, have too many iems, and just wasn't that concerned about how long it took.
As for the iems. They look fantastic, fit even better and sound just as great. Kozee is offering a phenomenal service for such a great price. I've had my TF10s back since the beginning of August and I am 100% satisfied with the job Kozee did. As for the TF10s...well, like most of us...they are good, but there is always better.
Thanks for listening,
