Worth it!
After reading a few reviews by beauty people I respect I took the plunge and invested in a ZIIP halo. I enjoy using it and see a difference in the texture and tone of my skin. I mostly use the 4 minute fix programme about 3 times a week. I feel a slight tingle in my teeth and under my nose so it definitely packs a punch! Not painful - just enough to let you know it’s working. I’ve not yet had to charge the battery. My only negative is the price of the conductor gel which has no added benefits. Otherwise, highly recommended (I’d rather buy this than have four mediocre facials)
