Doug's D453-ss

I cant speak to the SS, but I was TTI distributor for a while, the rust issues killed TTI, and trying to get warranty across the border, I essentially gave big cash refunds OR replaced them with Doug's, - no charge, then fire saled used TTIs for cheap.
I have never regretted the change-over to Dougs, and haven't had a quality issue thru prob 15 sets over last 20 years.
I wouldn't hesitate on the quality record, but can't speak to SS.
Good Luck, keep us posted pls.
