Review: Works awesome....so far - This was a second attempt to buy a good karaoke machine. The last one, Masingo brand, the mics didn't allow any kind of distance from the base. More than 2 feet away and the mics would stop working. After reading some reviews, I gave this one a go. Boy am I glad i did! First of all, I really like the compactness and portable nature of this unit. Very easily schlepped around. The unit is very sturdy and well built, don't see anything external breaking soon. Had no problem connecting our devices via bluetooth. The sound is amazing! The sound is clear with a good bass, perfect for a house party or backyard party. The mics are fantastic! They have controls for a speaker volume, mic volume, echo and voice enhancement. The only time the mics cut out was when someone other than the singer was standing right in front of the speaker blocking the signal to the singer. The unit says that mics can reach up to 10 meters. In reality, the singers would and should be closer than this distance. We had no issues with being about 15 feet away from the speaker. The unit comes with the standard wires to plug into the wall and/or usb ports for power and charging. Haven't had the unit long enough to test battery life from a charge. This unit was totally worth the extra money. Hopefully, it will hold up in the long run.
Review: Great Speaker, EXCELLENT customer service - After doing a considerable amount of research, I bought this Karaoke Machine last year and could not be happier with my purchase. It's not my first one as I bought another highly rated system 3 years ago that only lasted a year and was slightly more expensive. The sound quality on this RHM speaker is impressive and a good quality karaoke machine with 2 wireless mics is hard to find. The system is extremely user friendly, comes with simple instructions and has provided my family and friends hours of fun! I love how easily transportable it is, so it's not a hassle to bring it anywhere and it holds a substantial charge. So much so, that when I didn't use it for awhile, I forgot what the charger looked like and tried to charge it up not knowing I was using a different charger. I contacted the company who QUICKLY responded and helped me troubleshoot the problem. I realized I must have misplaced/lost the original charger. Though it's my mistake, they are kindly sending me a new charger. Honestly, I don't write reviews very often but the customer service was so outstanding, that I had to share. Great product and next level customer service!

### ⭐⭐⭐⭐⭐ Great Machine and Customer Service
*by M***A on August 31, 2023*

We were pleasantly surprised with the sound of this karaoke machine. It sounds great, and has impressed relatives that have used our machine. Overall, it is a pretty solid karaoke machine. However, about six months after purchasing the machine, one of our microphones stopped working. I contacted their Customer Service Support, Gina Ma, and have since been blown away by her outstanding customer service. When I reported that our microphone stopped working, she replied almost instantaneously and asked that I provide a video of the issue, so that they may assess whether they could assist in fixing it or send a replacement altogether. In just a short period of time, she reached out to me with the tracking number of our new microphone. Coincidentally, when we received the replacement microphone, our other microphone stopped working as well. Again, I reached out to Gina Ma with a video of the new issue. She responded right away, and after assessing the video, informed me that they will be sending another replacement microphone. I have been very impressed with Gina Ma’s customer service and I am happy to have this machine.
