Thank you for commenting! I am glad that the post was helpful for you. I still use both devices interchangeably and quite often, and I still love them both. I use them based on skin needs, and I do not use both of them on one day.

What I do is that for NuFace Trinity, I use at least twice (sometimes three times) a week at night. This device is mainly for toning and lifting. For Ziip, I mainly use it during the morning when I get ready. It has some quick programs, such as the instant gratification, which only takes 4 minutes. I use it when I need a quick pick-me-up. Another program I really like from the ZIIP is called sensitive energize. This is a longer program (12 minutes) and I use it at night when I feel that my face is sensitive. This program also tones and lifts, so if I use this, I will not use Nuface. What I like about Ziip is that you have so many program options to choose from, and most of them are not time-consuming. I feel that many of the programs are suitable to use in the morning, such as Primer (2 minutes), instant gratification (4 minutes), vitaleyes (4 minutes). You can also use when you have specific skin concerns, such as sensitive energize (12 minutes; I love this one the most), pigment (treat/prevent sunspots), total clearing (treat/prevent acne or bacteria), quick fix (treat pores), and 11S (treat forehead lines). I cannot testify for the results of functions such as acne or pigment because I do not suffer from those issues. However, I do use those programs to prevent (I use those functions very occasionally though). All in all, it all depends on what functions you need, and whether you want versatility in the tool. Based on my experience, I am happy that I have both tools and I do use them constantly, so I feel that my money was well-spent. Please feel free to let me know if you have any other questions:)
