Since June I have this set in use. I have deliberately waited to write a review actual. I can assure all who wish to establish a wireless chime access back to one of these devices. Certainly the price is only one relatively high. However, it receives absolute thoughtful craftsmanship that keeps what is promised for the first time. After I've already placed three cheap radio gongs from the Far East to before purchasing Grothe Mistral, all after 14 days some had a defect and therefore mostly useless were the current purchase an absolute blockbuster. I can only recommend this product and it rings still ;-)
