I have been a loyal customer of Martin gmbh für umwelt- und energietechnik for many years, and I can confidently say that their services are average. While they have a good range of products, their customer service can be inconsistent at times. The staff is generally friendly, but I have had a few instances where my concerns were not addressed adequately. Overall, I would recommend them if you are looking for decent products and are not too concerned about exceptional customer service.
