Okay, after reading the original post...
I'm not an entrepeneur or a mechanic. Nor am I interested in starting a new business to replace Mike's XS, even though they sold me a part that doesn't work and won't return my money.
Yes, I read the terms. However, I think they should update their website to indicate that the non-returnable electrical part they sell DOES NOT WORK on my specific bike even though THEY SAY IT WILL. Or it's defective. Either way, I can fark arf and they keep my cash for the part AND the shipping. I don't like paying people to sell me useless shit that doesn't work.
So, as a simple rider and consumer of maintenance parts, is there a reasonable alternative to Mike's so I can "vote with my wallet" and take my business elsewhere?
Appreciate any recommendations.
