This toy was great for me for vaginal penetration by a partner and alone. I would not use it anally because it is not flared, thus making it unsafe for anal use. The silicone is very firm, and the texture is impossible to ignore, so if you're afraid it might be too much for you, it probably is. (Thankfully, there's a Tentacle Jr version from Whipspider with less texture that is smaller and slimmer.) The curvature of the tentacle makes it a good G-spot toy, and the wide base even allowed some clitoral stimulation while being penetrated. It is also fun for nipple stimulation, but I suggest using lubricant with that as the silicone has a lot of drag to it.

The silicone is quite firm, and the texture is very rough. Honestly, it hurt the first time I used it, and the next few times it was still very rough, but I didn't have a problem with it as I enjoy rough sex of many types. The sucker texture is really sexy for those of us who enjoy a tentacle fantasy here and there, and just feeling it on my breasts and legs was a turn on. I suggest using lubrication (not silicone based!) for this toy because it does have a lot of drag and it is pretty rough. On the positive side, it's strong enough to stand up on its own, so if you can figure out how to hold it still it would be very effective for attaching to a chair or shower wall. The bottom is a bit concave, but not enough to hold suction with lots of movement.
There were very few flaws in the silicone, and it isn't compromised by manipulation and movement. It's a really quality toy, and totally body safe. Because it's silicone, it can be sterilized by boiling or washing in a 1:10 dilution of bleach.

It was smaller than I thought it would be, but I'm kind of glad! It is very filling, and the shape is effective at G-spot stimulation as well as stimulation of the clitoris and nipples. It's probably not for beginners, but I think it's a beautiful addition to anyone's collection. It's worth buying just for the craftsmanship alone, and it makes a great display piece! It is only discreet if the people around you are completely naive and unimaginative, but most of my friends weren't 'offended' by the design (mind, I'm only friends with sex-positive people). It's pretty 'realistic' as far as tentacles go, and I prefer this design over the more squid-like one from Bad Dragon.

I'm sure there's a harness out there that will fit this, but I don't have much experience with harnesses so I can't make a recommendation. It would be pretty damn sexy to see this thing attached to a harness, though. I really enjoy this toy, but I have to be in the mood for it. It's only a warm-up toy when used externally because that texture and steep curve can be overwhelming if you're not ready for it. I honestly didn't think I would be that turned on by it visually even though I enjoy tentacle porn, but seeing it move over my body was kind of fantastic.

Since this is silicone, it's pretty easy to take care of. It can be washed with soap and water, boiled, or rinsed with a bleach dilution or toy cleaner (silicone safe). Don't use this toy with silicone based lubes, as that will degrade the material, and be cautious of storing it so that it touches other silicone toys. I simply keep it sitting on top of my desk, and I give it a quick rinse before use to get rid of the dust and fuzzies that silicone loves to attract.

The packaging was a simple plastic bag, which was visually disappointing, but it did save on packaging. It can be reused for storage or travel, but I don't use it for daily storage because I don't like scooting it in and out of the plastic because it rubs the silicone. It probably wouldn't damage it, but this thing is my baby and I'm kind of cautious. There were no instructions, only a business card from Whipspider.
