“ I just received a new generation of ISEE. I haven’t encountered any situation for a week. I feel more fluid and stable than the previous generation. They finally joined the cloud and added the song. The measured speed is still satisfactory! I am very satisfied with this product for the time being. !"

​“ This is a great karaoke system, I originally bought this for my daughter but it works so well we have used it for plenty of parties with friends and families in our home. There are decent numbers of songs for us to play or download, it is perfect for family, letting kids karaoke their favourite songs. You will use this more than you think.

“ The quality and sound of the songs are better than the karaoke machines I bought in Taobao. It doesn’t have many processed songs! The most worthy of appreciation is that Guangdong songs are very new and numerous! The function and gimmick are not as many like the one I bought before. But the practical functions are all available, and this has become a plus point!"
