NumaLift™ Sculpt & Firm Device

I do like using this to massage uplifting products skin products hoping it does create desired effect think can see improvement straight after using but not sure abour long term effects. Also annoying that it only came with a spanish manual? So i only use the red light as unsure what others are for and how to tell how long to use each session and when i mught know it needs recharging. I messaged for a manual in enhlish but didnt get any response. But I am using as stated above and think its more convenient than using fingers.
