NXG Microphone Wireless System I purchased this but have had no opportunity to use it. I'm selling it in "like new" condition, having only used it for fun in my room 3-4 times for 15-20 minutes each time. It was working comfortably. The product listing at the time of purchase indicated "NXG," but this is not specified on the main unit or the outer box. I am a novice and do not have much knowledge, so I cannot answer detailed questions. I am unable to provide after-sales support, and I will not accept any claims, returns, or refunds, including issues related to shipping.
