We started out with more of a novelty cock ring, one that was less than $5, just to see how we'd like it. It turned out to be a wonderful experience. We were hooked. Then we noticed that the overall run time was "up to 40 minutes," this would not do!

We shopped around for rings with replaceable batteries, which seem to be somewhat rare. We came upon the Lelo Bo...rechargeable! This sounded like it was for us!!

The Lelo Bo is a very soft, very stretchy device. Elastic enough to grip, stretchy enough to be wrapped around only the base if the penis, the scrotum, or both! The vibrating unit is covered in the same material, but still seems a bit hard. The corners are a bit more squared than I would picture for an item like this, but it did not seem to pose a problem. My problem is with the vibrator not having enough soft covering. After 10-15 minutes of vigorous use, it did begin to chaf my penis where the vibrator "box" came into contact with it.

The Lelo Bo is made of a soft, super stretchy material. The stretchiness allows for a comfortable fit for a smaller penis (such as mine) up to (I'd imagine) an upper average penis. It stays in place, even during our most vigorous testing. Discomfort can be caused by the somewhat harder vibrator box.

Easy to put on and stays in place. The vibrating unit stayed at the top even during vigorous intercourse. Easy to turn on, simply slide the vibrating unit into its interlocking position and it automatically switches on. Shutting it off can be a bit trickier since it snaps firmly in place. It's quite difficult with all the lovely fluids and lubricants covering it. It must be disassembled to shut off, charge and store in the nifty storage case.

It is powerful, yet quiet. Barely noticeable in the throes of passion. Powerful enough for wifey to exclaim, "This has got to be one of the best inventions ever!". Hubby barely notices the vibrations during deep penetration, but it is quite noticeable and pleasurable on the out stroke, when she'll let the pressure off of the clit long enough to BE an out stroke! Powerful enough to enduce orgasms for her, not so strong that it's numbing for him. Win-win.

Cleaning is easy with a mild soap and warm water. It can be discreetly stored in the included hard plastic case. It can even be charged while in its case! Multi-colored LEDs make it easy to know when it's charging or charged, but kind of kills the discreetness.

The Lelo Bo comes in a very nice multi-piece box with fitted plastic compartments. Something you might find a really nice pocket knife or something like that in. That box is black with a simple Lelo embossed on it. Discreet enough for the top of your dresser or nightstand. That box comes in an outer box, colorul yet tasteful but has a picture of the product, so not something you'd want to leave out.

We have only purchased two vibrating cock rings so far, but we find the Lelo Bo to be powerful, quiet, discreet, well made and worth its heftier price over more "novelty" rings. We may suggest a disposable one to see if cock rings are for you and if they are, the Lelo Bo would make an excellent addition to your bedside arsenal.
