Pros: 100% waterproof. The "power bullet" vibrator is outstanding, and located directly in the part that goes into your bum. You will feel the FULL vibrations. Silicone. No odor. Hypoallergenic.
Cons: It's on the smaller side. If you like something bigger, this may not be the toy for you. It's also a bit pricey, but you get what you pay for.

jopen ego e4 big

A new breed of prostate massager

The Jopen Ego E4 is a new breed of prostate toy.  Jopen makes sex toys for the high end market, and they didn’t disappoint when they went all-out in designing this model.  It’s completely waterproof and very easy to sanitize and clean.  The soft silicone design is almost seamless.  It has no odor and is hypoallergenic.

Good, powerful vibrations

It’s a little more powerful than other massagers we have reviewed.  So, for you gentlemen who like a little more “buzz” in your toys, this may be the ticket for bedroom bliss.

It’s rechargeable!

Another bonus:  it’s rechargeable.  No worries about replacing special sized batteries.  This is a great feature for those who are environmentally conscious when it comes to disposable batteries.  It also goes for quite awhile between charges. On the high setting it lasts between 50 and 60 minutes.  On low, you can expect a little longer:  up to 80 or 90 minutes. Not bad at all.  It will fully recharge in about 3 hours.

Another vibrating massager we like is the Nexus Revo 2.  It vibrates AND has a rotating head that gently bumps the prostate for a significant pleasure boost!

We love the USB recharging cord

One of my favorite features?  The recharge cord has a USB connection. You can plug it right into your computer, if you desire. No fumbling around for a special charger to plug into your wall.  This is perfect for home or travel use. IMPORTANT: there is no wall plug-in that comes with the unit. However, since most of us have cell phones, you may be able to use that plug if it has a USB port.

It’s a smaller diameter device

A note on the size:  it’s on the smaller side, so if you’re accustomed to something with a little more girth, this may not be the device for you.  This makes it a GREAT toy for beginners, or for those with a little less room in the bum.

It comes with a 1 year warranty!

Jopen also backs their products with a nice warranty.  For a full year after purchase, they will replace a defective product.  This is much better than the industry standard.  See the vendor for more details.

The thing we like most about the E4:

The vibrating mechanism is in the perineum end of the massager.  It’s a little different from other devices that place the vibe into the insertable end.  We like this because it vibrates both the inner AND outer areas at the same time.  A spectacular sensation to say the least.

Something to consider:  the vibes going into the prostate may not be as strong, since the vibrating action is on the outside.  We feel that they still make their way into the insertable end quite nicely.

A real review from an Amazon purchaser

Great, powerful vibrations. Inserts comfortably, though newbies may need to take it more slowly. I found it most pleasurable in the missionary position while sitting up. Still felt great in others but there was something stronger in that position.

Additional thoughts

This unit is a little different, in that the vibrating mechanism is in the insertable portion (the part that you insert into the rectum) versus on the perineum side (like Rocks Off products).  This targets the vibrations straight into your bum and into the prostate.

It’s fairly quiet.  I’d compare the noise level to that of the Lelo Billy.  It’s not noticeable at a distance.  You could use it in your bedroom and nobody would hear it outside your door.

All in all, this is a WONDERFUL prostate massager that’s built with durability and quality in mind.  It should provide years of service.

We highly recommend this anal lube:

passion water based lubeThis natural water-based lubricant by Passion Lubes is our favorite.  Easy clean up, and compatible with all toys.  Inexpensive, too.
