I had a mixed experience with Bartl wärmepumpen. While their customer service was excellent, their product quality was average at best. The product I purchased started malfunctioning within a few months of use. However, the company promptly replaced it and provided great after-sales support. Overall, I recommend their customer service but advise caution when it comes to product quality.
