I just ordered an experimental set from them with a low F# (.174) BEAD. I ordered Saturday, and didn't get an email indicating they were shipped. I called Weds, the guy said they were shipping out Weds, and on Thurs I got the confirmation. On Saturday I got the strings, so 1 week turnaround for stated 2 day shipping. Really not that bad. The strings are awesome, I got the new Steels. Smooth and super responsive and punchy, even on the huge .174. I also checked the sizes with my nice carbide faced Mitutoyo calipers (i work in quality for a machine shop so I was curious) and they were +/- .001 up and down each string, save for the tapered ends. They also answered the phone when I called and were helpful and efficient. I have ordered 6 sets of Kalium (Circle K) strings over the years and never had a problem.
