I received this for my birthday to replace an older system and I checked tons of reviews before purchasing. It works with all my purchased CDGs and hooks up to my TV no problem. I was able also to hook my laptop up to the TV and play Karaoke songs from Youtube on the tv and sing through the speakers. Fun! I did not test the flash drive or Bluetooth yet, but the slot in front of the CDG drive makes a nice spot to keep the case for the "in use" CDG.Microphones have long enough cords that singers can sit further from the system on the furniture. Volume control is separate for the two microphones which is nice if one person wants to be louder or softer. Speakers work great and are plenty loud enough for a larger size room with a bunch of people. There are silver screws and black screws provided for assembly. Keep them straight because although they will fit in the same holes, some are longer than others and length does make a difference! Voice of experience. Easily rectified but thought I'd put that out there.The speakers and pedestal are pretty lightweight which makes for great portability but my daughter has a German Shepherd and an Aussie Heeler and they were playing and nearly knocked the machine down. It is stable but a bit top heavy and can easily be knocked over by a careless dog or a small child, and the machine might not survive the fall, especially on a hard floor. I think the only thing I would change about this machine is to make the platform base wider and heavier, for that reason.I was able to purchase songs from the Singing Machine website and burn my own mix as a CDG. LOVE that as I've had trouble finding enough songs I enjoy on commercial CDGs and sets to warrant the purchase price, without duplicating songs I already have. This way I only buy the songs I like. Songs end up being about $2 each and for that you get the vocal and no vocal track for each song you buy and the option of multiple formats. I had a little trouble figuring out how to select the correct format to burn to the CDG at first. There is a link on the words I didn't see at first that let me select and download the right format in my purchased songs folder online. Burn at the slowest speed your machine allows like it tells you. The burner on my laptop worked at 10x.I burned Christmas CDGs and we used the machine at our church Christmas party without the mikes for a sing-along with the words going on the TV and the music playing (They had traditional and non-traditional fun ones. The Grinch Song was a hoot and a half by the way). Room was the size of a small gym and you could hear to the back with people talking.I love that this machine is affordable but not cheap looking or sounding. It's obviously not a professional system for recording but for family and party use it's fantastic! Very happy.
