Marketed as a G-Spot vibe, the Harmony Radiance is the sister to the Divine vibrator. With a much smaller diameter than the Divine, the Radiance seems much more usable for anal stimulation as it doesn't feel very fulfilling during vaginal use. Call me a size queen but I think many women enjoy some girth from their insert-able toys. There is a fairly decent curvature to the toy allowing access to the G-Spot but due to the small diameter of the 'ball-type' end of the toy I found it very difficult to find the mark that would drive me to orgasm this way. The hard plastic construction makes for extremely easy cleaning after use and both water or silicone based lubricants slick this shaft up wonderfully for simple insertion. Decent vibrations emanate from the tip of the vibrator and transmit well along the whole length of the Radiance making it a good choice for clitoral stimulation. Controls are simple even with slippery fingers.

For anal use the lack of a flared base means the user must be cautious to avoid losing the entire toy inside but the curve and ball end allow for prostate play and this has been the ultimate end use for this couple!

Although hard plastic doesn't come close to mimicking any body part that I've encountered it does make for some advantages. The smallest drop of lube makes the Radiance super slippery and easy to stick anywhere the sun doesn't shine. Smell is also not an issue with plastic either and whenever the airport comes out with 'vibrator sniffing dogs' they will still have a difficult time rooting out this toy! The same goes for taste as well, with zero noticeable effect on the palate for those in the habit of slicking up a toy with spit or putting on a show for their lover.

Other than the ball end of the shaft which has a very small ridge the Radiance is smooth as a cue ball with no seam lines from the molding process to scratch up your naughty bits. My only real complaint is the same that I had for the Harmony Divine sister vibe. The toy feels a bit cheap because it's so light. Heft = Quality. While easy on the wrists I wish the Radiance had some more weight to it to make it feel worthy of the price it commands.

Measuring in at slightly over 8 inches in length, the Radiance has about 6 inches that can be inserted until you hit the push button controls. They are not raised much and don't impede further entry of this toy. The diameter is lacking for vaginal insertion in my opinion at about 1" at the head and slowly tapering upwards along the shaft. Maybe this will be more comfortable for novice users experimenting with finding their G-Spot but it caused me trouble and I couldn't have a good vaginal orgasm and desired some extra girth.

The curvature of this vibrator is comfortable and not excessive and should help with access to the G-Spot but it didn't for me. The hard plastic is unyielding and doesn't simulate any cock I've had the pleasure of encountering but makes for good transmission of the decent vibrations from the motor.
Again, the size seems much more suited for anal play, particularly P-Spot stimulation and that's ultimately the use we settled on for the Radiance.

Vibrations from the Harmony Radiance are decent but certainly not earth-shattering. Four different intensities are possible ranging from low to high with easy push button adjustment. Press the "positive" button four times to cycle to high, then the "minus" button four times to completely turn the motor back off. I always rave about push button controls because no matter how slippery your fingers are, setting the power is still a breeze. The vibrations are centered at the tip and do transfer along the entire shaft fairly well without causing your hand to become numb while working the toy. Sound isn't whisper quiet, but also not a train wreck. Anyone listening through the bedroom door would know what I was up to but I wouldn't be keeping them awake!

The Radiance lived up to its waterproof claim well and even after submerging in our hot tub for over half an hour there was zero moisture inside. Just be sure to tightly close the battery cover before any water activities to make for a good seal around the internal silicone ring. The battery cap is a little tough to grab due to it's placement at the end of the toy, it's curvature, and it's small size. My fingers had a hard time grasping it but my ever helpful hubby gave it a good twist after battery installation.
Speaking of batteries, this vibe will need two AAA's which have lasted us for over an hour of total run time thus far.

Care and cleaning of this vibrator is simple with a wash in soapy water taking care of business. Just be sure to give a little extra care along the ridge separating the ball end and the shaft because if anything is to hide out, that's the spot it will be! While hard plastic is almost completely non-porous I still wouldn't recommend sharing without covering with a condom as this toy can't be boiled and soaking in bleach will cause the control pad to chemically break down over time. Water or silicone lubricants can be used with this toy and contact with other play things in your arsenal will not cause compatibility issues. Still, we always separately store all our toys in zip-lock bags to prevent contact. To us, it's just a good habit!

Doc Johnson packages this product in a decently attractive plastic box with the vibe clearly visible through the front window. Although I wouldn't use it as a gift box or for long term storage it's not cheap looking and doesn't have any tacky looking porn stars lustfully gazing at the consumer.
No instructions are provided nor are they really necessary other than statements saying that the Radiance is waterproof, takes 2 triple A batteries, and that the cap must be closed tightly (to maintain waterproofing).

It's also noted that the Radiance is available in both Yin and Yang colors which somehow to the people at Doc Johnson means black and white...

This vibrator has been put through its paces in the two weeks we've had it thus far. From the perspective of G-Spot stimulation, it just didn't cut it and trust me, I really wanted it to work for the intention in which it was obviously designed but without luck. For external clitoral stimulation I did manage to have a couple of orgasms but they did take some time and my husband's help giving some nipple stimulation and vaginal penetration at the same time. Now anyone who follows our reviews knows we enjoy anal play and my husband has become quite an aficionado so it just seemed fair that he would get a try with the Radiance. Guided by my expert hand, with the ball of the toy inside him about two inches, he was in bliss with the stroking of this vibe across his P-Spot. Aided by my loving lips around his cock he reached an orgasm in no time flat with the vibrations and pressure of this toy stimulating his happy place. So the Harmony Radiance is no longer mine but his and something he has brought into the shower on two occasions so far for me to work my magic! Don't worry, I keep a good grip, don't go too deep, and don't share this vibrator that has found a comfy home in his butt.
