I found that this Groovies Wave feels very nice when used on your clitoris for some fun foreplay with a partner. I have also used it by myself and I love to use it on my clit, running it up and down my labia and then inserting it just a small amount. Since this toy is on the smaller side, it is great to stimulate the lower portions of the vagina and feel the waves of the toys curves. I found that using the Groovies Wave on the nipples is very stimulating especially when you run it from the clitoris to the nipples and back down again.
This toy has 8 different settings to pick and choose from and you're sure to find one, or maybe a few, that will send you on to waves of groovy sensations.

I think that any one of the 8 settings could be used to ease tired feet at the end of the day. Just roll it on the floor under your bare foot to release the soreness brought on by the day. You could easily use it to release stiff, and sore back muscles.
You may even use it to ease colic in a baby! You could roll the toy over your baby's tummy gently or have the baby sit face down on your knees and roll the toy over his/her back.

The small size of the Groovies Wave should not cause any marks or discomfort to even the most novice user.

The texture of the Groovies Wave has a very nice, smooth, velvety feel to the touch.
It does not seem to have any smell to it and there does not seem to be any taste to it either.

With the velvety coating it does seem to glide easier for my use, but each person is different, and you may find that you need to use some form of lube.
It is hypo-allergenic, latex free and phthalates free, these three things make it pretty much useable by anyone.
It is made of plastic with a velvety coating to give it that nice feeling. It's jewels are very nice to look at but I did not find them to be of much use to the toy.

The design of the Groovies Wave allows for you to pin point one place with the tip of it, where the vibrations are felt the most, and riding out the groovie wave of orgasm. I found that this toy found just the right place and the vibrations it made were outstanding.
The size of the Groovies Wave is 5 inches long with about 4.25 inches being insertable. It has a circumference of 3 1/4 inches, and a diameter of 1 inch. It weighs 0.2 lb and is a nice size, as well as weight, for even a beginner to use.
I found it easy to travel with because of the size. It is easily hidden in a hand bag, or even an over night bag.

The Groovies Wave has 8 settings that are sure to make things all groovy.
The 1st one is a light vibration in the tip of this toy, not very strong at all. You can feel the vibrations through the base but they are most concentrated in the tip. This setting and maybe even setting 2 could be used on the temple to help with a tension head ache.
The 2nd is a bit stronger in feeling but still mostly felt in the tip. It travels to the base but not felt deep in the toy mostly on the surface more than anything.
The 3rd is stronger and if your clitoris is very sensitive could be a little more than you like to feel. It could even cause some numbness or burning in that case. It does, at this level, start to have a bit of a higher pitched sound, but still not too loud for use in your shared dorm room or in your bedroom.
The 4th is a bit like riding the hills of a roller coaster. The vibrations work up to a high speed then back down to almost nothing. It starts out low and works to high.
The 5th one gives you short pulses of medium intensity with very short breaks before it pulses again.
The 6th gives you a faster pulse but seems to feel a little less in intensity than the last setting.
The 7th goes back to a study vibration close in intensity to setting 2.
The 8th, the one that I think is the best of all the settings, seems to be a random pattern of all the 7 other settings. You never know what you will feel next and that makes this one of the funnest ways to play. The level of intensity seems to be a little stronger than before but still very gentle.

While testing this Groovies Wave I have used it in the shower, washed it in running water several times, dropped it in a sink full of water, and used it in the hot tub. I have not found any water has leaked inside the battery compartment at all. I also have not seen that there is any leaking around the push button controls on the bottom of the toy.
The battery housing is lined with paper showing how to install the 2 "AAA" batteries. The batteries fit very snugly and do not bang around while being used.

The push button control on the bottom of the base of the toy makes it very easy to use and change the speeds while playing alone or with a partner. I didn't find that I hit the push button while playing unintentionally but it may be possible to do. The only draw back is that you have to go threw all 8 speeds to turn off the toy.

I use warm water and a mild soap to clean this toy, or a commercial toy cleaner. You could use 10% bleach and water solution.

I did find that this toy does use batteries quickly.

You can use pretty much any lube you would like to with this toy since it is not made of anything special other than the velvet coating over the plastic.

I do not store my toys without wrapping or putting them in a box separate from each other to keep them from harming any other toy. Some toys can interact if stored touching so always check that out before storing your toys together.

As with any porous toy you should use a condom if you plan to share with a friend. EdenFantasys does sell small [https://www.edenfantasys.com/sex-essentials/sex-toy-cleaners-and-wipes/toy-covers]toy covers as well as smaller size condoms for toy use.

My partner found that this Groovies Wave even felt good to be used on his scrotum while receiving a blow job. So this is a good toy for either sex.
