Took a bit longer to kick in than I expected, but once it did the warming sensation was intense in a good way. The 50 ml bottle is a decent size for the price.

Wasn't expecting much, but the warming tingle kicked in within a minute or two of applying it. The pump bottle gives you decent control over how much comes out, so no mess. It's water-based too, which means it cleans off easily and doesn't stain.

The water-based formula absorbs quickly and doesn't get sticky like other gels I've tried. Noticed a real tingling warmth within a couple minutes, and it washes off easily afterward.
