Cthulhu Tentacle Dildo

Good for vaginal use, not so good for anal
I bought it for stretching anally, but didn't look close enough to see the fins on the side. I ordered in Medium firmness thinking it would be fine, but turns out anally the fins just hurt. So I don't recommend for anal!
Since I am a dude, I can't personally speak for its vaginal use, but can relay the thoughts (and moans) of my partner. She is very happy with it, to say the least. It's one of her favorite dildos. The fins are her blessing to my crux. She also says popping over the final bit down at the bottom in intense riding sessions is one of the most satisfying things about it. Really well designed Dildo!

PROS:
Good vor vaginal use

CONS:
Not suitable for anal

good well made product, we ...
good well made product, we didn't really take the sizing into account and should have gone for maybe a smaller size, but still great fun

PROS:
large base for good support,

Excellent product!
Excellent product! This is definitely my favourite model so far. Stunning signature colour and the ready-made version arrived as pictured.

PROS:
Excellent quality and shape - the frilled edges are particularly unique and fun!

It's a challenge at first. Be sure you order it with a Vac-U-Lock hole for a suction cup to make it easier to control. Well worth the small added cost and a must on any toy, really.
PROS:As always, Sinnovator does it again with Cthulhu. I welcome variation of the standard tentacle, this guy is thick, textured, and curved in just the right place. The tapering makes for a nice, gradual insertion. My Iridescent Violet to Sinnovator Black fade turned out beautifully (as usual), making this a very handsome sea monster.
CONS:I've yet to come up with any disadvantages on any Sinnovator model.

Absolutely Fantastic.
Absolutely Fantastic. Decent length for how thick this one is. I got this one in a small, and Im glad I did. I tend to bite off more than I can chew when it comes to fantasy toys. This one is fast becoming my favourite of the ones I've bought so far.

PROS:
Feels fantastic. The ridges are so so good!!! Medium soft was a great choice.
Great for sizing up from the small Cephalopod for a slightly different feel if you like things with a little more girth.
Makes some fun noises when in use.
Easy to clean.
Custom colours, as always, are fantastic and never disappoint. ( I opted for Neon Orange and Black fade again)

Very good looking!
Very good looking!

PROS:
-Very soft and flexible (On the medium soft option)
-AMAZING craftmanship
-great texture
-I ordered the 'Surprise me!' colour option, and the colours ended up AMAZING with a marbled effect for half the price

CONS:
-Only issue is the girth, but that's because this is my first monster dildo. If you're new, you'll probably need time to stretch it out, because it's too thick to go in easily without pain.

very very sexy toy, i already wrote a review but writing another as i can't update/edit the original review.
This is one very sexy toy, it slips in very nicely and with a little patience (boy i was tempted to go faster) the girth was no issue particularly because its medium softness allowed it to adapt to my shape.

PROS:soft yet strong, very smooth and some unique sensations.
different sensations depending on orientation when inserted.
sitting down ont he toy once it was home produced some very squishy sensations which actually felt like the things was alive.

CONS:none really other than it could have a little more girth and a little more length.

take your time to get fully inserted and then it really will give you some fun.
PROS:great feel, great sensations and a lovely softness that is just about right once its found it's way.
i notice a few comments about the girth being quite big - i found it just about right and entices thoughts of going bigger.
it may just be me but once fully in it makes some amazing squelching noises while riding with plenty of lube.

CONS:it's a little bit challenging to get this toy too go in the right place when going solo, until the first couple of inches are in then it nicely finds its own way.

amazing toy for people who love odd things and aren't faint of heart.
Medium soft has the correct amount of squish to it although the next purchase may need to be just the medium firmness so then variety can be used. This was bought as a present and to fulfil kink desires and well it does the job and fulfils more than what was expected. The size does look terrifying but if lubed the size doesn't feel the way it looks. The way the details feel give off that extra feel making it feel even more pleasurable and stimulating that increases the deeper the toy gets.
PROS:- amazing feeling,
- the texture is amazing,
- size is definitely there in girth and length,
- sturdy material
CONS:- none at all

It is a great toy ...
It is a great toy to play with, it was a a little bit too big at first but after a few tries it was perfect.

PROS:
Perfect firmness, not too soft and not too hard. Perfect size. Beautifully made by Adam! Quality is amazing.

CONS:
nothing.

Bought this with the pjur relaxing gel and after some great customer assistance from Annie via message function to amend the order, it arrived 2 days later.
Mrs is impressed and happy at the 'right amount' of squish on medium soft and the gel helped it get where it was going comfortably so its definitely on the regular use list until we decide which others to get.
PROS:Mrs is impressed and happy at the 'right amount' of squish on medium soft.
CONS:Absolutely none so far.

Great toy but not for the feint hearted
PROS:Great quality toy, the marbled finish is appealing to the eye
Gives a nice stretch and firm enough to slide down, in fact once inside your half way down before you know it. The ridges and rubs give great pleasure and stimulation that increase the deeper you go
CONS:None, though wish I'd ordered with the sucker cup as although it's heavy once it's inside it doesn't want to come out

Absolutely loved playing with this and showing off the results online!
PROS:Amazing ridges and detail. Silicone has just the right amount of give.
CONS:Could do with being a bit longer, a bit wider with a thinner base
