The SSA Glass Bumpy Spiral Double is a glass dildo best suited to those women who really love texture. It feels nicest with slow, gentle thrusting, and it targets the g-spot beautifully. Due to the firm nature of glass, as well as the pronounced texture, it's important to exercise caution during use, as overenthusiastic thrusting with hard materials can bruise tender areas.

The Bumpy Spiral does not provide a flared base, and is therefore not recommended for anal use.

Those users who enjoy the sensations produced by intense texture will fall in love with the Bumpy Spiral Double. For those who have never tried more a pronounced texture, this dildo provides two different choices to sample, but texture isn't for everyone, and for some, a texture that feels amazing one day might prove irritating on another.

Glass is a great material for temperature play. Rest the Bumpy Spiral Double in a glass of cold water for a thrilling chill, or warm it up for a different sensation. Never put a glass toy in the microwave, or use it fresh out of the freezer -- extreme temperatures might not hurt your toy, but they will damage more valuable things, like your tender parts. Play safe!

Speaking of safety, glass is phthalates-free, non-porous, and body safe. It can be boiled or bleached for sterilization, so it can be shared between partners.

A fall onto a hard surface could break a glass toy, but Pyrex glass will not shatter in the event of such a tragedy, but rather break into chunks. Sad, yes, but not dangerous. The human body is not strong enough to break a toy while in use, but it's still a good idea to check for stress fractures or chips before each use.

The Bumpy Spiral Double is a pretty toy of moderate size, which feels much larger in use due to the extreme nature of the texture, as well as the firmness of glass. It offers enough curve to easily target the g-spot, and provides a variety of intense sensation from two differently textured ends.

While not completely discreet, since many people will recognize it as a dildo, it's not a particularly realistic toy, so more gullible snoops might be convinced it's a tool for darning socks.

As for travel, it wouldn't be my first choice, but it's small and won't cause any sort of a ruckus by making your luggage vibrate. Packed carefully, it might even survive TSA's baggage handling.

Both textures on the Bumpy Spiral Double are intense, which limits the speed of thrusting, but creates quite a bit of sensation from even quite slow and careful movement. The curve is perfect for g-spot stimulation, either with slow thrusting or with a gentle rocking motion.

Glass dildos can be boiled or bleached for sterilization, or washed in hot, soapy water for everyday cleaning. Resting a washcloth on the bottom of the sink can help protect your toy if you should drop it during cleaning, but the texture of the Bumpy Spiral makes it easier to grip while washing than many other glass toys.

Storage is easy, thanks to the included red velvet separator bag. Just take care that it doesn't have room to clank against other glass or metal toys.

The Bumpy Spiral Double is compatible with any lube, and while most glass toys require very little in most circumstances, I find that a couple of extra drops makes the texture must more pleasant with this particular toy.

SSA Glass toys arrive wrapped in a layer of bubble wrap, inside of a lovely red velvet separator bag that is ideal for storage. The presentation is nice enough for a gift between intimates, although it's not the sort of gift you would exchange in mixed company.

I really enjoy the Bumpy Spiral Double, but only some of the time. I've discovered that texture feels wonderful sometimes, but quite irritating on other occasions, and it takes a little bit of experience to figure out when to use this toy. Unlike my other glass toys, I do need to use lubricant with this one, at least on the spiral end.

So, I recommend this toy, but not universally. Anyone who is bothered by textured toys should give this one a pass, and look at the Deep Water G instead.
