The Harmony Will Bring You Peace and Harmony!

I don't like that rechargeable batteries don't work with it, but I love everything else about it. Including the speed options.
Four speeds, waterproof.
Rechargeable batteries don't work with it.

extremely useful review


The Harmony is a four-function egg vibrator. The vibrations are just steady vibrations growing in intensity as you use the simple controls. This toy is best for clitoral, nipple, and over all-body stimulation. I would suggest against pulling on the cord of this toy, and it is connected well, but you could easily damage the wire if you pull too hard.

This is a toy that need little to no instructions to learn how to use it. It is a decent size which ends up making it suitable for anyone to use. You can use it for all over body stimulation on a male or female. If you're new to sex toys or have a large collection, this toy would be a great addition. You could use this egg in just about any situation.

Being on the smaller side, you could bring it with you just about anywhere. The lower levels of vibration (1 & 2) are quiet enough that you can't even hear them through the sheets. The higher levels you can hear through the sheets but not a closed door. The Harmony is waterproof, so feel free to take it into the shower or bath.

Be very careful about where you place this toy. Do not drop it hard or from a high height. The mechanism inside the egg that makes it vibrate is suspended. If you drop it, you could potentially make the connection break inside, and you have just ruined a great toy.

Material / Texture

This egg is made of plastic, which is rated a number 8 here on Eden. Plastic is non-porous and a phthalate-free material.

The Harmony is smooth hard plastic. There is no drag to this toy at all. It's very slick in use even without lube.

There is no smell to this toy as well as no seams. I feel a though this egg will last me a while, and when it does break down it would be worth getting again.
    • Smooth
    • No odor
    • Not porous at all

Design / Shape / Size

Here is the sizing of the toy as a whole.
The egg: 2 3/8 inches
wire: 30 1/2 inches
battery pack/controls: 5 inches

The length of the wire is long enough to use this egg in any situation. You may need to tie some of the wire together to make it shorter if you are using it for solo play. But for me I like the length, it gives me a lot of room for position options.
    • Partner play
    • Beginner

Functions / Performance / Controls

On the lowest setting this egg could please even those with the most sensitive clit. And on its highest it will be pleasing for those with a not-so-sensitive clit. I'm not saying this egg is rock-your-world strong on level 4, but it is strong enough to be felt through a pair of jeans, undies and a comforter. The whole egg vibrates, though the vibrations are even stronger when you are holding the top of it against your spot of choice.

The controls are just an up and down push button arrow. Completely covered to help to make it waterproof. Controlling this toy is pretty explanatory. The only time I had problems with the controls was when my batteries were on their few minutes of working. It would shut off, but I could still be able to turn it back on for about a minute.
    • Easy to use
    • Multiple settings

Care and Maintenance

You can tell what the Harmony is just by looking at it. If you want it to stay private, I suggest storing it in a place where no one will go looking. It is small enough to tuck between clothing in a drawer where no one can tell it's there. The Harmony still continues to drain the batteries if you keep them in, I suggest taking them out after use.

To wash The Harmony use antibacterial soap and hot water, your favorite toy cleaner, or by wiping down with isopropyl alcohol.

If you want to use lube, you can use any kind that you wish to you. It doesn't matter if it is water based, silicone, or oil.

The Harmony takes two AAA (triple A) batteries. I did find that you can not use rechargeable batteries with this toy, which was disappointing. I'm not sure if it was just the brand I used or if it is with all rechargeable batteries. I tried to use Energizer rechargeable batteries.
    • Easy to clean


The packaging is very simple. By all means it is not discreet. You can see the toy right through the front of the package. It is very cute packaging, but bulky for such a small toy.

There is very little information on the box. Just what the egg is: "Waterproof, multi-speed vibrator. ABP plastic. Phthalate free."

Personal comments

The vibrations of the Harmony were as I expected when it came to type of vibration. I expected a steady 4 speed egg, and that is what I got. The vibrations are deep, but I won't really say throbby. You can feel that the vibrations are suspended inside of the egg. I was able to get a good 8 or so sessions ranging from 10-45 minutes on one set of batteries.

This egg is one of my all time favorite toys now. It's one of my go to toys. I love how versatile it is, in terms of all the surfaces you can massage with it. I would even say that if vibrations on your temples help get rid of headaches, this would be a good thing to have around!
Follow-up commentary
This toy is still one of my favorites! There have been no problems with it at all. It is still in full working order. The only thing I have noticed is some of the paint on the buttons is starting to fade. The light in the toy tends to shine through the buttons now, which I don't really see as a problem. It's just kind of disappointing that I've only had it 4 months and the buttons are wearing down already.

    Great review! I am glad you enjoyed this, though it is a bummer that rechargeable batteries won't work in it.. I wonder why that is, though.

    Thanks for the review

    Thanks for the great and very informative review!

    Tigerkate: I believe that rechargeable batteries don't work because of how the inside of the cap is. It's flat on the inside and rechargeable batteries are completely flat on the negative end, making them not connect.
  • Fuck it.
    Thanks for reviewing!
    I didn't know that about rechargeable batteries? Are they all like that, or just the ones you have?

    nice review ^^
  • VampKitty
    Thrill, I've only tested Energizers rechargeable batteries. So I'm not sure about the other types.
