The Lilo Elise (I have the original white version) is comfortable, powerful, easy to clean, has great controls and...
... in the hands of an expert will extract cum from a stone (or a turnip take your pick). The shape is excellent - it can be positioned to ride it on or directly over the prostate with an incredibly powerful (and variable) vibration. The shape is vaguely phallic but somewhat feminine and extremely effective. The satin finish is great. The silicone rubber coating makes it easy to clean and sanitize, as well as completely safe.

On a certain day in May of 2007 I had never had a prostate orgasm. On that afternoon an incredibly talented woman took a Lilo Elyse vibrator and a lot of lube, gave me not only my first prostate orgasm, but my 64th (over the course of an hour and a half). I kept cumming and cumming and cumming until my sphincters were in rictus (basically the had contracted so much and so forcefully they could not relax.) It was almost overwhelming.

This is now a permanent fixture in my play kit - just remember to recharge it. One nice thing about Lilo is that every one of their vibrators takes the same charger.

Since that day it has given me literally hundreds of orgasms (p-gasms).

I clean it carefully with disinfectant soap and hot water (remember to close the little tab over the recharging wire hole) if you are going to wet it.

It can get pretty wet, but is not designed to be fully immersed in water - so you can't really take it in the tub, pool or hot tub, but I would risk it in the shower.

The power and different settings give a great variety of stimulations.

This vibrator just works.

If you are going to use it for anal, play use a condom; it makes cleanup a lot easier, and plenty of water based lube.

This is still my favorite vibrator. It has plenty of power, is rechargeable and can travel easily. I love that all Lilo toys use the same charger.

I never fail to come when I have this vibe stimulating my prostate.
