I've used Probe Thick and Rich for both vaginal intercourse and anal sex with silicone toys, and I've found it more than suitable for both. When used during love making, my wife and I required only a small amount, since it acts and feels much like her own natural lubrication. As for anal sex, Probe is ideally suited. It stays put when applied to both toys and skin, and we encountered none of the irritation, burning or sketchy sensations we found in other lubes.

Probe Thick and Rich is clear in color, and its consistency is thick, gooey, and stringy. This may sound like a negative thing to some, but believe me, it works. When used during intercourse, it Probe seems to blend perfectly with the lubrication already there. It lasts, it does its job, and you'll never know it's there. This thickness is also a great advantage when used for anal sex. Unlike thinner lubes, it won't drip or run away to unintended places. It will also stick to silicone toys without beading off or evaporating before doing its job.

Probe Thick and Rich is unflavored and has no discernible smell, a plus for those who find flavored and scented lubes too cheesy. But since everything has at least some taste, I'd describe Probe as slightly citrusy, and not at all unpleasant.

Probe is a more than adequate lube in every department. As mentioned above, it held up perfectly during intercourse. We needed no extra applications, and it needed no thorough clean-up or washing.

For a water based lube, it held up almost as well during anal sex. It applied well, it was more than adequately slippery, and it didn't irritate or burn sensitive tissues. The only weakness I could detect was that it tended to get a bit tacky after ten minutes or so. The good news, however, is that it required only a small re-application to renew Probe's original slide.

As for its packaging, Probe is functional and informative. There is no plastic or fancy space-age box to create unnecessary waste, and the label on the back describes Probe's uses, features, and ingredients.

On top of Probe's already excellent performance rating, it is also a perfect choice for those who are as concerned with health as they are with effectiveness. Thick and Rich is made of all natural ingredients such as vegetable glycerin and grapefruit extract. It is also paraben free and hypoallergenic.
