It is typical for a dealer to tell a prospective client that their lower qualitybrand is just as good as the more well-known brands. They will also say that the components are all the same regardless of brand. Most of these claims are false.
Major manufacturers are more selective in recruiting and training dealers. They have local technical support and are dedicated to 100% customer satisfaction. This is not true with all brands.
