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! Review: Great little karaoke machine - This a powerful little karaoke machine that I travel with all the time and take to parties, camping, friend's get togethers, etc. It connects easily to any bluetooth compatible device and you're good to go. I've had this product for over 2 years and it's still going strong. It charges fast and lasts for several uses. the carrying handle and loops to hold the mics keeps this really compact and easy to take anywhere I go. I've gone to many different karaoke studios and the sound on this one rivals some of those. It has little buttons on the mic itself that allows you to control the echo and volume. It's definitely fun for all ages. Highly recommend. ## Features - 【RICH, BALANCED SOUND FOR EVERY GATHERING】Experience the depth of 60W balanced audio designed to fill your outdoor space with clarity.

When not in use for karaoke, it blends perfectly into your bookshelf as a premium Bluetooth speaker for relaxing background music - 【SIMPLICITY FOR THE GREAT OUTDOORS】No complex wiring or technical headaches.
