Here comes the part you have been waiting for!
The throbbing monster has a plastic control bottom first of all, with a tight battery case I have to fight with every single time it comes to changing the power source! I live in fear already that I am playing around with toys which need me to use a fork to dig the batteries out of their case, keeping me worried constantly what in the world I am doing...! Because my not extremely long but nicely grown nails all BREAK when I attempt it without my good dining tool, and that would be ok if I didn't have to do it so often.
But the fact that this toy GOBBLES BATTERIES LIKE NOTHING I HAVE EVER SEEN BEFORE already had me change it since the day of receiving and turning it on for a few seconds, becoming totally drained after a few second of use next day! That next day is today at the moment, which consisted of putting in another set of 4 AAA-s, which also got drained in seconds (they were used already though, in another vibe which ran on full power before I took them out), so I had to recharge the first set of batteries again to be able to try this annoying monster. After putting them in I experienced the same weird thing, and put it aside frustrated as hell, turning to other toys of mine.
Finally I figured out how it works! So the obvious part is that there are the buttons on the bottom controlling part, two on the top for the vibration and two on the bottom for the throbbing. Flashing lights inform you about the current patterns and functions going, which can be turned on with the ON button for the throbbing, and the BULLET ON/OFF button for the vibrations. ON for the throbbing will also increase the speed, being able the offer three of them, and the 7F button will go through these vibration patterns:
1. low constant vibration
2. medium constant vibration
3. high constant vibration
4. escalation
5. high pulsation
6. pulsation of two short medium and one long high pulses
7. fast high pulsation
I should have put all low, medium and high into quotation marks, because they are rather barely a hum, somewhat a buzz and awfully low. Even if you check it out behind the thick rubber head of the clit attachment you won't experience better results. So that part served a different purpose for me, ending up to keep the USB bullet I was using to stay in place, at least it was good for something...
So there are no problems with the horribly weak vibrations. They work each time I turn them on. Always the first pattern coming on, which means the toy doesn't remember the last function used. The same expected reliability can't be said about the throbbing shaft...
When you turn it on it throbs like crazy, and you are like yay, I can't wait to try it! I had the same enthusiasm, all warmed up already and getting to slide it into its right place, ready to turn it on when it's there. I did. You know what. I could feel the throbbing for about TWO SECONDS. I had to realize that I was going to write my second review in a row about a toy which I also cannot call a vibe (as you probably noticed), and what also stops working even if I arch my inner muscles just a WEE LITTLE BIT. It is even worse than the thrusting toys, because it doesn't even go on when the pressure is off of it. It COMPLETELY STOPS WORKING, and not only the throbbing action but THE VIBRATION TOO. I am writing it with caps because maybe it is a safety function, but it is totally outrageous! And you haven't heard it all! Because YOU CAN'T TURN IT BACK ON TOO! The vibrations come back on just fine, but a tiny squeeze with your hand is enough to stop the entire toy, and you will see that often the throbbing can't even be turned back on after that, and you have to wait for a while until it can come back on for 2-3 seconds. SHAME ON THE MANUFACTURERS!!!
So I can say that unless you are an extremely sensitive size queen who wants to use a girthy enough dildo with a totally weak vibration in the pretty clitoral arm you will be glad to have this toy! Just don't turn the throbbing ever on, because it must be draining the batteries in an eye blink! I almost forgot to add something... The throbbing effect makes as beastly noises as its size is, but as it won't work at all you will have a silently humming vibe only, so you can use it right next to your sleeping precious! And dare to drown it into your tub! Even if it isn't waterproof like it says who will regret it? You have a RABBIT DILDO!!!
