Ordering is easy, like most sites. However, its when there are issues is where RevZilla really shines. Sometimes the parts just don't fit like you would want or the gear isn't what you expected. RevZilla takes has always been responsive and they take care of it quickly. So many store fronts (and people) are just so unresponsive when an issue arises, not RevZilla in my several years of experience with them.
As noted above, responsive and took care of the issue within a day. Consistently good.
