This toy came in a box with the toy on the front cover and a name different from Hammer X. I absolutely love this! It's fun, playful, sleek, and a beautiful Sapphire blue for my blacksmith ^.~ The vibrations and patterns are strong and travel throughout my body perfectly. The "head" of the hammer can be used for clitoral stimulation, which, as stated, is very strong! The "handle" is a nice, thick, rounded phallic shape that fills all the right places and has a light spiral carving all the way down. My partner, who I chose this for and whose birthstone is Sapphire, happens to work with tools for a living, and this was the perfect toy for us.
The vibrations, while on and not inserted, might be a little loud, but not by much. We were honestly surprised by how quiet this toy actually was, with two vibration points on either end!

There are 3 speeds and 7 patterns, making 10 different modes in total. Since the clitoral vibration is at the head of the toy and the handle is vaginal penetration, you might need to reach for a wand or another stimulation toy, which I had to do.

The "hammer" itself is very sturdy, silky soft to the touch, and has a limited amount of mobility. The silicone feels so soft against my skin and instantly gets me in the mood. I always use lubrication with my toys, vaginally inserted or anally. I find that a small amount of water-based lubricant helps keep that buttery soft feeling like new. You'll want to steer clear of silicone-based lube and store it with other silicone toys, as this will end up melting the toys together or melting the toy because of the lubricant.
The battery power lasts for a while. I used it fully charged and non-stop until it died, which was 2 and a half weeks of use, cleaning, and side table storage. I believe with constant use, you're looking at 3 to 4 days of battery life daily. That's a good frickin' battery if you ask me!
