Cool gadget but too costly
cool. 120$ is high .. cant buy
Same here..Can’t spend that much
Very cute
I think $120 is pretty reasonable for this gadget… (or maybe I’m just biased because I’m a frustrated music mixer)
Depends on you dear that how much u want to spend
I saw a viral video on youtube of someone performing (singing and mixing music) using this gadget.
It looked so cool and unique
