I don’t think your “review” on their service and quality has much of a leg to stand on considering you a) did not give Voltaire a reasonable amount of time to fix the problem and b) broke your contract.
You bought a modern, cushy, delicate saddle (with arguably the least durable upgrades available) and then did an about-face when it didn’t wear like a warhorse rock-hard saddle from the previous century. AND you didn’t let the rep adjust the fit or vouch for their product… In my neck of the woods one week would be VERY fast for getting a rep out, especially during show season.
For what it’s worth, I own a 2014 calf, second skin Voltaire Palm Beach that I sold my 1993 hard-wearing pigskin Hermes Oxer to buy. The only reason I bought the Voltaire with those features is because I ride one horse per day and knew I was going to baby it until said horse retires (and if anything went wrong in the meantime our lovely local rep will fix it). I did the rockhard wears-like-iron saddle route…I’m much happier with my pillow saddle now, even if it does have a shorter life expectancy.
I think you’ll probably have a similar experience with Devoucoux…except they don’t pick up the phone when leather falls apart or you need to return a saddle (trust me, I’ve tried!).
