Testimonials

I've been a customer of Lancershop since soon after I purchased my Evo 8 in late 2003. I've done some business with one or two other MastaMinds internet storefronts, as well. After my latest experience, I had to drop in a testimonial!

Due to what had to be MY error, I ordered the wrong part for a spring prep for the racing season. It was quite a while before I finally ripped open my boxes to get to work. When I saw I had the wrong part I was pretty disappointed and figured I was stuck with it because it had been so long.

When I e-mailed in to verify exactly which part I had so I could sell it to someone who could use it, Natalie in the support department stepped right up and offered me an RMA for full price credit!

I was floored and elated!

They have an awesome selection of excellent parts, good prices, and now I know, some of the best service around!

Thanks MastaMinds!
