I feel like I waited a while to finally give this one a try because of the mixed reviews, but when it went on sale I knew I should try it.
The Zini Roae is a silicone vibrator that is shaped for dual stimulation. It is rechargeable so you never have to worry about batteries and offers different patterns in addition to multiple levels of steady vibrations. The size of this one is pretty average so it should work for a variety of users. I have read other reviews that talk about how the size/shape did not work for some people's anatomies so it is important to take that into consideration (unless you are not worried about it working for dual stimulation). The handle will prevent this one from being sucked in by accident by your anal muscles, so it is possible to use this toy anally as well.

The silicone of the Roae is very smooth. It does not have a lot of drag and, at least for me, it didn't require as much lubricant as other silicone toys do. It reminded me of Lelo silicone in this way. You may still want to use a little lube to get rid of the drag. Water based is the only kind that should be used with this toy because silicone may damage it. Although it is smooth, it is rigid and has no give. It also can't be flexed to better fit one's anatomy.

The shape of this vibe is such that (if it works for your anatomy) it can hug your clit while being inserted to stimulate your g-spot or just your vagina in general. I was glad that the shape worked for me because when fully inserted I don't necessarily need to hold it for it to stay in place.
The shaft has a slight upward curve for better g-spot targeting. It has an insertable length of 5 inches, which may cause the bulge to miss your g-spot or make it uncomfortable to insert fully without poking your cervix. The diameter is a moderate 1 3/8 inches, so the size should work for a variety of users. The handle/clitoral portion curves up above the shaft (kind of like a candy cane, but closer together). I am not really sure what this shape reminds me of, something from a science fiction movie is my best guess.

The Roae is controlled by buttons that are on the handle (near the part that can be used to stimulate the clitoris). This vibe offers steady vibrations and patterns. It has a + and - button that can control the 5 levels of steady vibration. It arrives locked, so you need to hold both the + and the - buttons down for a few seconds to unlock it. After it is unlocked one push of the + button will turn it on and the - button will decrease the speeds and turn it off. It you hit the O button in the middle, you switch to pattern mode and can use the + and - to go through the 10 patterns. It is hard to describe all of the patterns but there are a variety of different pulses and escalations that utilize all 3 motors (one in the bulge, one closer to the end of the shaft, and one in the clitoral portion). To get out of pattern mode hit the O button again.
In my opinion, this toy sometimes feels like it has 2 motors, one for the shaft in general and one for the clitoral part. I tend to not need to use my vibes on the higher levels when I play, but for some reason the vibrations in the Roae are not extremely strong so I find myself turning it up higher. It gets kind of loud on higher levels and the vibrations are on the fence between rumbly and buzzy, so this is important to keep in mind.

When your battery is getting low, simply plug this one in and let it charge up. I really love not having to buy batteries on a regular basis. It takes about 2 hours to get a full charge, which will give you 4 hours of play time!

To clean, simply use soap and water or toy cleaner. It can be sterilized for sharing by wiping it down with a 10% bleach solution. NO BOILING because it will ruin the motor. A word of caution when cleaning: Do not submerge because the Roae is only splash proof. I accidentally dropped it in the sink while cleaning it and even though it wasn't under a lot of water, some still got in the charging port. I let mine air out and it was fine, just try not to do it.

I spent more time trying to figure out how much I actually liked the Roae than I have with other toys. The shape works well for me because I am able to feel the bulge in the shaft rubbing on my g-spot while having the clitoral portion rest nicely on my clit. Because I have to insert this one fully to get the desired stimulation, I don't have a lot of room left to get a good grip to thrust it. I like to move my toys, no matter if they vibrate or not. However, this is not my main complaint.

I really just wish that the steady vibrations were one vroom stronger in the insertable portion. My clit doesn't need super strong vibrations (this motor felt strongest to me), but internally I like them strong. The patterns were different and I could feel how the vibrations moved between motors on some of them which was a lot of fun. If you enjoy patterns then there will be at least one that you like with this toy. These 2 complaints together are why I wish I could give this one a 3.5 star rating, but instead will give it a 4 because I still was able to enjoy the Roae and orgasm with it.
