The Black Panther is a gorgeous black glass vibrator. Its angled tip is intended to stimulate the g-spot, and its sleek, smooth glass exterior with rippled corkscrew design allows for easy insertion especially when twisted. This vibrator offers a variety of unusual vibration patterns sure to satisfy.

The Panther is good sized, and will be enjoyed by anyone who likes more fullness with their toys. It isn’t overly heavy, and shouldn’t tire your hand out during use. It’s best used when discretion isn’t necessary since it is very loud.

Because of the tip shape and lack of flared base, the Panther should not be used anally.

This vibrator is splash-proof but not water-proof, and care should be taken not to submerge the base in water.

The Black Panther consists of a tempered glass sleeve over a vibrator. The glass is smooth and slick, with no noticeable seams. The glass is a lovely shiny black at the top, and appears clear at the bottom above the base, although the underlying vibrator is black. The vibrator is not meant to be removed from the sleeve and appears sturdily attached.

The Panther somewhat resembles a soft serve ice cream cone with swirls that run down the sides to the base. The swirls, which have about a 3/4" spread from crest to crest, add some sensation when the Panther is thrust and provide stimulation when the vibrator is twisted and twirled inside.

The Panther has no scent and no taste.

The Panther is 8 1/2” long, with about 6 1/2" insertable. It is a pleasant and filling 1 5/8” in diameter. The shape is wonderful – the running swirls allow the Panther to be twisted while inserting, although you will want to make sure the g-spot tip is angled correctly when it is inserted to the desired depth. The tip can be felt inside and rotated to the correct position.

The black base is almost 1 1/2" long and unscrews for battery insertion.

The Black Panther is powered by 2 AA batteries. They are inserted by unscrewing the base and slipping them in positive side down. The batteries are both easy to insert and remove.

A single push button is located on the bottom of the base. It is not too easy to push, although the vibration pattern can be changed by accident.

Pressing the button the first time turns the Black Panther on at a steady, high vibration. The vibration is concentrated in the tip, but can be felt nicely all up and down the shaft.

Pressing the button repeatedly gives the following patterns:
- Fast pulse
- Steady medium vibration for 10 seconds, 20 fast pulses, steady low vibration for 10 seconds, 20 fast pulses (repeats)
- 6 high medium pulses, 5 shorter pulses, 20 shorter faster pulses (repeats)
- steady high vibration for 10 seconds, steady medium vibration for 10 seconds, steady low vibration for 10 seconds, and then back up through medium and high
- 3 fast pulses 1 long pulse, repeats, then three long pulses (whole series repeats)
- 20 short fast pulses, then 10 seconds of high steady vibration (repeats)
- off

The Black Panther is incredibly loud, due to the vibrations being transmitted by the glass. It is best used with some background music on to disguise the sound.

The Black Panther is made from tempered glass, so it is non-porous and hypoallergenic – although a condom should be worn if sharing the toy. It is also resistant to cracking and shattering.

The Panther should always be examined for cracks before use, and should not be used if any defect is found. It should never be thrown on the floor or hit against hard objects, and should be stored away from other objects in either its storage bag or box.

The panther can be used for temperature play, but it should only be warmed under water (not the base end) and cooled in the refrigerator or freezer (and it should never be left in the freezer for an extended amount of time). Never put the panther in the microwave or cool it with dry ice.

The Panther can be cleaned with antibacterial soap and warm water, or with a sex toy cleaner. Water-based, silicone, and oil lubricants are all safe to use.

The Black Panther comes packaged in a large white box with product visible through the front plastic window. Other products by Glassvibrations are featured on the side. The back of the box has product information in 6 languages.

The box lid is held on by magnets, and lifting the lid reveals the Black Panther nestled in a cardboard frame that is covered by white satin. It is held in place by two elastic rings, and a tied white satin ribbon.

A black drawstring storage bag is included. The bag is soft but thin and un-padded.

Two AA batteries are also included.

The Black Panther is made by Glassvibrations, a German company.

The concept of vibrating glass has intrigued me. It’s not a material I associate with vibrating, but I’m happy that it works so well. This vibrator is a successful marriage of the smooth feeling only glass can provide and the multiple function stimulation only a vibrator delivers. The glass transmits the vibrations nicely, and it just takes a little lubricant to make the Panther nice and slick.

The texture of the Panther is nice. The ripples can be felt internally for me, and provided an interesting sensation when the Panther was twisted in and out. Glass is hard and unforgiving, so I had to be careful with how hard both my husband and I thrust this. We also had to take care that the tip was in the right location. It worked especially well with shallow thrusts.

The vibration patterns on the Panther are different from the typical dit-dit-dot of most vibrators I’ve used, and all are enjoyable. I do wish there was a separate on/off button since there are quite a few to cycle through.

My husband didn't care for the base on this one, as when his hand was covered with lube, it was tricky and slippery to hold on to.
