karaoke machine recommendation please?

Does this mic work well? https://www.amazon.com/Wireless-Bluetooth-Microphone-Portable-Handheld/dp/B09V899BQ7/ref=asc_df_B09V899BQ7/?tag=hyprod-20&linkCode=df0&hvadid=675656294136&hvpos=&hvnetw=g&hvrand=5130114294847939569&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9032008&hvtargid=pla-2249797057581&mcid=820f84ef09f5325f945c0d8ef23afb1d&th=1

could three of this mic be used at the same time?
