We really like the Leadsinger, and the only complaint we have is that the music sound quality isn't as top rate as other systems are. I knew this would be the case because someone else reviewed this product and stated that--how the guitars are replaced by keyboards, etc... so I wasn't disappointed but it's a little distracting at times is all.Soung selection with the product is great (the 300 that come programmed) but we can't wait to buy a few more cartridges!
