Vivido Elping High-Frequency Massager

I'm watching Lotte Home Shopping right now, and they're broadcasting the BB high-frequency treatment device. It's being advertised as a special summer promotion, and the show host’s words are really tempting. They say it's a product that doesn't feature product placement or advertising. It looks like a full-body massager for areas like the belly, arms, thighs, eye area, and neck. They claim it provides elasticity care with powerful vibrations reaching deep into the dermis. They say they're giving away two units only during the broadcast. It has a lot of features—high frequency, ultrasound, microcurrent, and even LED. I'm really curious to hear real reviews from people who have actually used this.
