I think this conversation could go forever with the posters who do have proof of their preferred kite capabilities out of the bag and their ability to video/photo the evidence and those who profess such evidence is irrelevant if the kite or related gear is half the price or less and their say so is evidence enough.
Unfortunately evidence is usually the proof required by most sane people when making the purchase of an unknown product. There are many sayings such as "Quality is remembered long after price is forgotten" and being a person who "knows the price of everything and the value of nothing". These phrases often come about by hard lessons in trying to get the cheapest product or service and finding out it wasn't worth it in the long run.
There are companies who are transparent about who they are and what they do even at opposite ends of the price spectrum. As a Flysurfer reseller it gives myself and customers a lot of confidence having one of the main people in the organisation, Armin Harich, publicly answer questions on many forums and explain and demonstrate his products on various video posts. Likewise the low cost, high quality French company Gong, whom I have no association with, who's videos feature the main people in the company. Not only the main bearded man Patrice but also Diane the Office Manager and Marine the webmaster. There must be a company policy that you have the passion for the sport to get the job
Meanwhile after all these years of seeing Pansh mentioned I am no closer to knowing who they are, why do they do what they do, is there any passion?, how do they do it, ie product R&D, and where is the evidence that their products measure up reasonably to their competitors. For all I know it's a Chinese company using free prison labour in forced labour camps to produce copies of other companies expensive R&D efforts with minor tweaks. I would like to believe this isn't so but there's no transparency, not even the slightest effort to contradict this notion. The "About Us" on their site is anonymous and looks like it was written by the marketing department.
In my experience, a good quality product that delivers on its promises, straight out of the bag or showroom is worth paying for. You get your money back in terms of enjoyment every time you use it and if you do sell the item, it holds its resale value. And you don't have to pay big money, just look at the Gong range of kites, foils and wings.
By the way snarky comments and insults diminish the poster, whatever product they're writing about. It just turns the focus back on the poster... and not in a good way.
