We've no problems at all, in fact we really WANT people to report both the good and the bad about any vendor, sponsor or not - which is why this thread has been here since 2008:

We as staff do not promote or favor businesses just because they're a sponsor, nor does sponsorship garner any additional benefits beyond having a graphic advertisement on this forum. That's all they are too - advertisements, we're not promoting them, they're promoting themselves and us through their sponsorship.
Just keep in mind while we exist to provide helpful assistance with any type of motorized bicycle - we are not a supplementary customer service department for attempted warranty claims and public disputes. We encourage vendors to assist people with problems encountered with their products, but when it comes down to arguing over wait times and money you're best served by contacting the vendor directly. If that fails - post the results (or lack thereof) here in vendor review so others can learn from your problems.
