My first impression was very good indeed. My guitar hadn't shined so beautiful since it was new. That said, I will never buy this product again.
The problem is the bottle - it leaks. I used to keep it in a trunk with other accessories and soon, I had the content all over the place. If it sits quietly on a shelf when not in use, it shoudn't be a problem, but in a bag or something with other stuff, it's a mess.
