Great product. Does exactly what it says it does. Very easy to use and excellent results. These trial bottles have easy to use spouts that eliminates spilling and keeps everything clean.

The Jax Darkeners do a very good job of covering up stripped coins. The black and black/brown work very well and very quickly. I'm still struggling with the green, but as noted on this site, the green is somewhat tricky. I personally like the look of stripped coins when I have to use electrolysis, but if you don't, then these darkeners (particularly black) are a must have.

Some good, some bad...OK, but could be better. I've seen alot worse products for more money
