I've had a Theiss hybrid for maybe 5-6 years for occasional IWB carry. It's still in great condition. Turnaround time for me way back then may not even be relevant anymore but I think it was a couple weeks. It's still the only IWB I have, last used it to dabble in IDPA last year. At the time I ordered Kydex belt clips which broke after a couple years, and i replaced with steel clips from amazon.
