😊 I have been a customer of Ral deutsches institut für gütesicherung und kennzeichnung e.v. for a few years and I must say that their products are average. The customer service is good and the staff is always willing to help. The website, ral-guetezeichen.de, is easy to navigate and provides all the necessary information. I recommend this company to anyone in need of reliable and durable products.
