I really like the puzzle. The Puzzle vibrator can change size. You can make it where it is large at first and gradually gets smaller. You can also make it smaller and get larger. Or you can alternate the rings, one big ring one small ring. This makes for a great feeling also. The top vibration is really strong. You can also set the vibrations to a low speed. Which is really good when you are just getting started. It comes with one extra loop so if you want it larger you can take one of the smaller ones off, and replace it with the larger ring. It only takes 2 AA batteries. If it took any more, I think it would vibrate me off the bed on high, The Puzzle vibrator is really easy to use.

It's clean up is not simple. Not difficult ether, just time consuming. If you don't have a drain catch in you sink be careful when you clean the tip. I almost lost the tip of my puzzle to the drain. Be careful of how tight you put the tip also. I have tighten mine to tight, and I almost could not get it off to clean it. If you find an order that you really like you may want line them up when you start to clean it. When you are looking at the individual rings it is hard to see the difference in the sizes, but... YOU CAN FEEL THE DIFFERENCE!!!

I would not suggest the Puzzle vibrator be use with anal penetration. You can feel the different size to every ring. Unless you are use to playing with large anal beads. I have not used anal beads yet but, I imagine it would feel about the same. I would suggest this toy to sexually experienced women. If you are looking for a different feeling this is the toy for you. It is a great toy for couples or singles. My husband and I like the fact it has a wide variety of vibrations. Good for any mode you are in. This is a toy you will use over and over no matter how many you have.

Grate for clit stimulation. Also nice to have it in the front while having anal sex. This will drive your partner crazy. If you choose to use this toy in place of anal beads. Use a condom. It is hard to clean the inside of the rings well. If you do not use a condom this could lead to infections.
