The hulking beast is certainly intimidating for beginners, and lives up to the name.
The material is a soft silicone, with a few veins for added simulation. Its easy to work in, and the knot doesn't swell as suddenly as a lot of similar toys. However at a bit over 6.5 inches around it may be a bit too thick for those who don't want much girth.
Its a bit too much for my partner, though a friend has enjoyed it regularly and enjoys the filling sensation and the vein on the back. The overall shape is particularly well shaped for vaginal penetration for anyone into thick knots and a werewolf or similar theme, and doesn't get in the way of the clit if right side up which is always important to us.
The suction cup is strong enough that we've joked about using it to climb walls, so that should be a plus to those looking at dildo mountaineering or hands free use.
I would certainly recommend this to anyone who wants a fairly girthy knot dildo, but not so much for beginners.
