MY 2 CENTS
I am in love with this top coat!
I bought it because my nail polish is always chipping, even on the same day I apply it. I’m not a big nail polish girl, so I’ve only tried top coats from OPI, Sally Hansen, and Wet n’ Wild; compared to these, Good To Go is a dream-come-true!
I’m on day 4, I’ve experienced no chipping and the color is still shiny and glossy.
My nails are normally weak and brittle but with this top coat, they feel strong and sturdy. They’re not breaking!
Good To Go doesn’t dry super fast but it’s fast enough (within 5-10 minutes).
The top coat has an almost gel-like consistency yet it’s thin and easy to spread. I like this because you only need a little to cover a whole nail.
One thing I would change about Good To Go is the brush. It’s very thin/small; you’ll need to swipe a couple of times to cover the entire  nail. I prefer a brush like OPI because you can cover your entire nail in one swipe.

The prices vary between retailers. Unfortunately, I purchased this at $11.99 because they were sold out everywhere I looked. I would still repurchase the product, though!
