Vince Saved Me!
5 /5
Vince had some really great options from me to pick on when first connecting with him. As I was checking out Vince was blowing my phone up warning me I accidentally selected the wrong board size. Seconds from selecting payout I cancel the order re selected the size and got to pick the right board for me. Thank you again Vince!

I've been shopping on curated and bouncing ideas off of Alex for some time now, never actually pulling the trigger. My budget has been hit and miss and often I've had to forego new in favor of used when it finally comes to the purchase. Alex has always been so helpful and ready to give advice on what gear is going to be best for me. I'm sure he'll be shocked when he sees I finally made a purchase 😅 thanks bud!

Tucker was responsive and helpful
5 /5
I've been looking to add new skis to my quiver after demoing Rossignal powder skis in Utah. I liked the demos but wasn't sure if they were the right choice. Tucker shared a few similar skis and one was the Atomic skis I had also demoed in WY. I settled on the Rossignal and Ticker also setup a bundle with recommended bindings for the skis. Overall, a great experience while making a sizable investment to enhance my skiing experience.
