The representative of this site uses the brand of another company-
5 plus , as I understand it , although it has nothing to do with it, except that it buys material from this company. He told me that he was a partner, but on the website of the manufacturer of the material with the same name, I did not find any information about him. I looked at the data on the site, it has been working for less than a year, although it is written on the same site that they have been on the market for more than 12 years. There is no office as such. In general, decide for yourself, but take into account the fact that after some time, you can apply for a warranty case and find only a real manufacturer's company, where no one will know about you and your case due to the circumstances!
