I use the golden gel primarily and I purchased the crystal gel to alternate. It’s very gentle, I prefer the golden gel but this is good to alternate with the golden gel.

Works great with ziip

It certainly has a lot of glide to it which is good. You can't spritz water to make it go a little further on your treatment and it's sticky.

So far I am truly loving my ZIIP HALO! It feels so nice while I’m using it. After doing the Founders Favorite I’ve actually noticed a difference in my dimples on the sides of my chin. My skin looks more alive after doing any full face treatment. It’s very comfortable to use, I actually enjoy using it, it doesn’t take long, so even doing a few treatments, one after the other, it isn’t all that time consuming. I love the gel, it last through multiple treatments, it doesn’t dry out or sink into your skin so you have to add more throughout your treatments. The only problem, rather not a problem but just a cosmetic thing, I’ve noticed at the edge of the chrome looks like there are small areas that look like they may peel or chip. They haven’t yet but I’ve just noticed it and hopefully they won’t. But overall I’m truly loving it.

Seems great to me. It's hard to tell a difference when you don't know what you're looking for. I have used the gold, silver and now crystal. All work well.
