I had the Marble Slimline G pegged all wrong. Now that I've finally figured out where my G-spot is, it has become one of my favorite G-spot vibes. It's slender enough for anyone to use, but the head is large enough for someone who's just started the hunt for their sweet spot. The strong vibrations and angled head are great for clitoral stimulation as well, and with some extra lube it may just work as a good p-spot vibe as well.

It can be used for solo play, or with a partner. Plus, it's waterproof, so you can play with it almost anywhere. You'll want to be sure to use plenty of lube because the plastic can be kind of harsh if you aren't properly warmed up. The seam may also pinch a bit if you aren't using enough lubrication.

As I already mentioned, this vibe is made of a hard plastic. It doesn't bend, which can be good and bad. You can pin point the exact spot you want to stimulate, but if it catches on your pubic bone it is going to hurt. I think the plastic definitely makes the vibrations more intense. It doesn't cushion them like softer materials would. This vibe would be an excellent toy for a beginner, but it would work just as well as an addition to the more advanced player's toy box.

The design of this toy is pretty simple, which makes it easy to use. The head is angled perfectly for g-spot or clitoral stimulation. I don't have a p-spot, and my husband hasn't quite warmed up enough for the size of this toy's head, so I can't tell you for sure how it would work for a prostate stimulator. But I think it would be worth a shot if you're feeling adventurous.

This toy is very slender, perfect for a beginner. You might not enjoy it if you prefer thicker toys, though. It's easy to hide in a lingerie drawer or under a pillow, and the perfect vibe to take with you on a trip.

The dial to turn this toy on is located at the base, right under the batteries. You definitely need two hands to turn it up or you'll wind up opening the toy and the batteries will fall out. Since the handle is so slender, it sometimes slips out of your hand. Especially when it's covered in lube. This can be frustrating when you're near an orgasm, since the toy has nothing to indicate which direction it's pointing when it's inside of you. It might take you a few seconds to figure out which way to turn it.

It's a little loud when it's turned all the way up. Not so loud that it would be heard in another room, but may want to take advantage it being waterproof if you share a dorm or bedroom with someone.

Since the Slimline Marble G is made out of plastic and waterproof, it's ridiculously easy to clean. Just plain old soap and water or before and after toy cleaner will work fine. I just stick it back in the box with all my other toys and lubes. No special care needed.

I had completely misjudged this toy originally. I've had it for a little over two years now. At first, I wasn't getting warmed up enough or using enough lube, so it was painful to use. The seam down the center of the toy pinches a lot if you're not careful. Once I sat down and used it properly, it became one of the best toys I've used.
