Product: The product was very easy to install and operate. Performs as described. Nice, clear sound and with many tune options. Seller: (I don't currently have the option to leave direct seller feedback on Amazon since it's been a while following my initial order.) I had an excellent product issue experience with the seller. The push button had been stuck in the "pressed position" without my knowledge and drained the battery (discovered after a visitor mentioned they rang the doorbell and I heard nothing.) I contacted SECRUI via email. After a few email communications regarding the issue, I was promptly sent a replacement button. Their customer service was both prompt and courteous.
