Honi operates on two buttons. The buttons are a plus and minus sign, but they are hidden in the "P" and "B" of the PicoBong lettering on the toy. I know some have had trouble finding them. I found them pretty easily, but I had also read in reviews where they were located.
The buttons are a little weird to me. To turn it on, press the plus button once. Okay, easy enough. Now, the manual says to turn it up you press the plus button once again. On mine, it seems to work better if you hold it down for a second and then let go. Basically, you have to hold it for a longer period than a simple press and release. It's just a frustrating control system because I'm used to a quick press of a button to change settings. To go back, press the minus sign. Once you reach the max power level, hold the plus sign for two seconds to get to the patterns. Press for two seconds to get to the next pattern. Use the minus sign to go back. To turn off, hold the minus sign for about two seconds.
The buttons are generally a pain. They aren't hard to depress down, but they are hard to operate. I had trouble getting from one setting to the next without getting annoyed. It seemed to respond differently each time. Sometimes I would just need to click and sometimes I would need to hold it down. I never did accidentally press them, so that's a plus. Another thing is that since it's a wireless bullet, if you decide to insert this, the controls are now inside of you. Think about that concept for a moment. If you want to change settings, you have to remove the toy to do so. If you're one to change settings a lot, this won't make the best internal toy. This is "supposed" to be an internal toy. I have to think it would have been better with a wire, even though I usually hate wired bullets. Having to remove the toy to change the settings just seems counter productive to me. Externally, it's not as big of a deal. The buttons are a bit hard to locate during use and you'll probably have to take the toy away from your body to change the setting.
The PicoBong site says that 18 clicks gets you from the lowest to the highest power setting. To be honest, I had so much trouble with the buttons that I could not count this out to verify. I'll just give you the intensity at the lowest and highest because I can't seem to make it go from speed to speed in a way that makes it feel like actually settings.
The lowest power is a low level one vibration. Highest? High level two. Yeah, you read that right. And yes, I double checked my batteries. I've read some reviews that rate this a three and even a four and I just can't do it. This is a weak toy. I used this internally during pegging and literally forgot I had it inside of me because I could barely feel the vibrations. Externally, once again the vibrations were just barely noticeable. It should be noted that I need a lot of power and I'm rating this against things like MiMi, Life, Salsa, and Tango. Nevertheless, it's just plain weak.
Due to the weak vibrations, it's hard to tell if they are rumbly or buzzy. My guess is more to the buzzy side as they feel very surface level. They do not seem to penetrate the skin very well. They don't cause a lot of numbing, but do cause some. There is a buzzy noise to them that is high pitched.
Here is a diagram of where the vibrations are located. I can really only feel them where you see the largest circle:
I'm no good at describing patterns, so I'm going to give you the diagram of them instead of trying to explain them and failing miserably at it.
As per the diagram:
Steady vibration
Pulse - Build and fall
Bold Pulse - Rock/Pulse
Mid Pulse - Quicker than Pulse
Flash Pulse - The speediest Pulse
Half Wave - Stimulating jolts
Flash Half Wave - Quicker, tight jolts
Full Wave - Fluid rise and fall
Flash Full Wave - Faster fluidity
Bunny Slope - Reverse Pulse
Roller Coaster - Longer, faster reverse Pulse
Bumper Cars - Spontaneous transitions
I don't use patterns, so I can't speak to the effectiveness of any of these.
The noise level is high given the power. It's louder than my cell phone on vibrate. It can be heard slightly through covers at the highest setting but not through a closed door. It makes a slight rattling noise.
As mentioned, it is waterproof to 1m. I have not really tested the waterproof capabilities of the toy to say for sure if this is true or not. It does not have an O ring, but rather an elaborate screw cap that I guess keeps water out.
You will need one AAA battery to operate Honi. This battery is not included. The bottom unscrews to reveal a place to insert the battery.
