Hi. I'm afraid you won't be able to purchase a TWS from the Promoted Pawn Website. We are sold out and I'm not planning on making anymore this year.
As far as the quality goes I've never had anything but positive feedback and never had anyone take advantage of the 30 day satisfaction guarantee.
A few of my customers have rifles that won't cycle properly on the very lowest setting- for others it doesn't cause a problem. The guys who had that problem didn't mind because they found the lowest setting to light anyway.
