I just got a great filter through an amazing transaction with @quantegy. Thanks for making it easy and painless!
Bought am module from @monokompatibel, it arrived fast and in very good condition. Sadly the module broke after a short time - surely not his or my fault, must have been a manufacturing defect. It was no problem to send it back and let him handle the warranty process with the original seller. Fast, pleasant and dedicated Trader. Big recommendation!
5 stars out of five for Heren! I just bought 2 modules from him, and it was great in every aspect - modules were exactly as described, prices were ok, delivery was fast, and the communication was very pleasant! Thanks!
