Yes agree, their implementation is punitive to the innocent consumer (who unknowingly or naively purchases their product from an online retailer from China/USA/France/UK/Spain/Or any other location for that matter) then have their product completely stop working one day.
Kingsong should fix their distribution network and sales channels, instead of punishing their failure to do so... on the consumers, who are have no knowledge of such trade/sales policies/disputes, they just merely want a product to enjoy for the life of the product.
By punishing end users/consumers, it will spread decent upon the company and its products. It makes consumers feel they have been cheated and have become the middleman of a proxy trade war / proxy distribution war / proxy sales channel war. The consumer becomes the victim and suffers from such actions. While the sales channel is left unpunished, and the manufacturer gains a bad reputation for being unfair to consumers for blaming and punishing them for their corporate problems and lack of control over their distribution network / sales channel.
By fixing their distribution network and sales channels, they will protect product sales territories with their distributors and retaiilers, while keeping sales channels happy and more importantly consumers happy (and they will spread the news of such products and good business practices... hence Gotway, Inmotion, Ninebot and Veteran have all preserved their good name and good will since they have NOT applied such bad business practices, despite them also experiencing such distribution network and sales channel challenges as Kingsong).
Kingsong really needs to make smarter business decisions moving forward from this point. Lots of damage done to their name and will loose plenty of future sales as the threat of Briking a very expensive toy is always looming over consumers head, and the betrayal of consumer confidence to this brand.
As the saying goes... the punishment does not fit the crime.... especially when the crime was committed by the manufacturer's sales channel/distribution network... NOT the consumer, yet its the consumer that got punished.
Gotway, Inmotion, Ninebot and Veteran, its your time to really take things up a notch and take the lion share of the market now! .... Kingsong is paving the way for you. This opportunity rarely happens in the business world. Make smart moves and one of you guys will take the market amidst the vacuum created by Kingsong, as consumers look for good products backed by good companies! Good Luck!
