This toy is, for the extremely reasonable price, a gem.
While a complete newbie may have problems getting started with it, if you know what you're doing it makes for some interesting exploration. Use lots of lube and don't rush it. Don't let the size throw you off if you are new to the sport. For this price you can afford to buy it and park it for while as something to aspire to later on. And you will, I promise! It really does feel excellent.
The only thing against it is there is no small diameter indent under the third ring to keep it inside so you will wind up holding it in place with your hand no matter what movement you undertake. It gets 5 stars anyway because price and pleasure outweigh that small inconvenience.
That being said, it is a pleasurably intense experience and is a great "opener" (sorry) for the larger toys. For instance after leaving this in at full penetration for about five minutes, I can go straight to my Dick Rambone with no strain.
All in all, a very pleasurable device for a ridiculously low price. I recommend it without hesitation.
