It's made of hard, beige plastic, that's rather body-friendly and safe. I actually love the fact that it looks like a retro 1980s vibe!
It's completely straight, not curved, which produces rather unique and hard penetrating sensations. Unlike a penis or silicone dildo, this will not hug your curves. While it's not quite as unforgiving as glass, it's close, so you can't always thrust super hard. It's of a modest girth, starting with a rounded point with a roughly 1-inch diameter that increases to a 1.5-inch diameter near the base. It has about 6 and 3/4 inches of insertable length, not counting the base. It's about 8.5 inches total.
The vibrations are strong enough, but not out of this world. They are strong enough to get me and most people off, however. If you like the feel of battery-operated plastic vibes usually, then this will work for you, as it produces vibes with about the same strength and feel. It's rather loud in proportion to the strength of the vibes.
The hand cranking process entails about the same level of awkwardness as hand-cranking my self-powered camping lantern. A little plastic handle pops out from the base; it seems too small to be very strong, but holds up well. This is very hard plastic. It's ergonomically made so that you just grab the rotating tip of the handle and make the same type of movement as if you were winding up a spool of thread. Getting the cranking started is the hard part, as there's a little resistance at the beginning, which will resume if you pause the cranking or slow down too much. But if you get your hand in the right position so that cranking can continue without pausing, it's pretty smooth sailing from there. The key is to avoid jerky movements, and it's easy to get a hang of once you get started. The red light confirms that your cranking is powering up the device.
Four minutes of cranking will give you about 30 minutes of vibes, and I've found this to be accurate. Four minutes of cranking will give you about 28 mins of vibes on the high setting. Of course, four minutes of cranking means four minutes with the red light on. The nice thing is that vibes don't lessen in intensity as the battery drains, at least not until near the very end of its life. It can also hold a charge for a while--I went on vacation for two weeks, and it was still charged up. It would be ideal if it had an external meter to show you how much charge it has, but as it is, you have to guess.
Three buttons lined up control the vibes. The central button turns it on and off; the button on the left lowers the intensity of the vibes, and the button on the right increases the intensity. Fortunately, they're not easy to accidentally turn off when holding the handle, but I do find the placement of the buttons a little confusing. It's not ideal for rapidly changing the strength of the vibes until you become familiar with the placement.
The instructions indicate that this toy is not waterproof.
Hard quality plastic is in one of the top safety ranges, but it's not sterilizeable like silicone. Wash with warm soapy water after use, but take care not to immerse it in water, as the instructions guard against it. Although it doesn't take disposable batteries, it does have an internal "power source" which is a rechargeable battery, so discard safely, or you'll un-green it. It looks built to last though, and I doubt many will ever need to discard it.
The simple clear plastic packaging is recyclable, but, of course, carrying that out depends on your local recycling facilities. It's definitely not a keepsake.
