Device is sold as a mini hifu, it is actually an ultrasonic pen with radio frequency and ems. It works great, is made well and shipped fast. It will take weeks before the rf will show any effect. However if you are looking for hifu this isn't it and the ultrasonic power i'm unclear on, but likely is only strong enough for product absorption.
I think it's a nice device for rf and help your skin absorb your skincare more effectively. It works better than other devices i have tested off of ali express. I like the weight, size and portability. It doesn't overheat a lot. It's just not hifu.
