My experience
I bought a Silverbullet a couple of years ago and then discovered it was too long. That meant that I had to deal with the business a second time. Both times, I found him slow in responding (probably two weeks or so) and I almost gave up. But, both times, he was great to work with and responded very quickly once he got back to me. He made a shorter, custom link and traded it for the original at no extra cost. I had even damaged one of the smaller parts in trying to install the original one, and he just sent along an extra at no charge. I don't know about now, but patience got me something I really like. After all, it wasn't something that was keeping me from flying.
That said, I jumped on a slightly used Silverbullet offered through the VAF classified a week or two ago 'cause I knew Paul wanted one and it was a more certain way of getting one for him.
