Sinfully Steampunk

If you're looking for something a little higher quality than most traditional vibrators, the Nagi is a good option. It's waterproof, has a variety of vibration levels, made with silicone, and is nice and soft making it good for penetration.
Powerful, quiet, silicone, sleek and sexy.
May be too thick for some, price.

extremely useful review


The Nagi silicone traditional vibrator by SinFive is a gorgeous piece of German craftsmanship. It needs only two AA batteries, is extremely quiet compared to other battery operated vibrators, has easy to use controls, and is completely waterproof. The smooth rounded tip, gradually widening, and soft silicone make insertion comfortable for anal or vaginal play.

The octopus design is unique and makes the Nagi a fitting piece for any Steampunk Lady or Piratess' collection. This is a great standard vibrator for beginners and collectors.

Material / Texture

The shaft is made from a soft, flexible silicone down to the battery case which is made out of a hard plastic. It does attract hair and lint, but not as much as the more velvety silicone (like Jopen toys) will. Nagi is slightly flexible, but doesn't maintain the bend once it's been let go. There is no texture on the shaft until the octopus decoration at the base, even then the texture isn't bold enough to be felt during insertion. Like all silicone, the Nagi has no smell or taste.

This would probably be best for someone looking for a smooth toy for easy thrusting or sensitive to texture.

Design / Shape / Size

I find the design of the Nagi to be really sexy. It is 8 inches long, 1 inch at the tip, about 1 3/4 thick at the base, and an insertable length of about 5 1/2 inches. The silicone is a sleek black matte with a white band at the battery case with the SinFive logo. It's pretty discreet as far as most vibrators go, probably because it is such a dark matte black and not some obnoxious neon glittery pink.

The battery case is probably the best that I've seen yet on a toy. The cap is super easy to remove and replace, it is CLEARLY labeled how the batteries are to be inserted with magnets holding them in place, and there is a nice little silicone ring that helps seal out water during submersion.

Nagi would probably be suitable for users of any level, although advanced users may pass this up due to lack of texture or size. The tip is rather thin (1") and the gradual widening of the shaft is easy to take vaginally and anally.

Functions / Performance / Controls

It is super easy to use the Nagi, thanks to the two buttons located on the back.

The (+) turns it on and increases the levels of intensity. The (-) decreases the vibration level. Holding down the (-) for a moment turns it off completely. There are six standard vibration settings from low to high, and three pulses to mix things up. The first two are throbbing patterns, they seem pretty steady and intense. The last setting is random. It seems to be a little bit of everything.

The volume of the Nagi is surprising low. When turned on to the highest setting, it gets about as loud as your cell phone on vibrate. Nagi gives out vibrations that are somewhere in between a buzz and deep rumbly ones. The main vibrations come from the motor located about 2 inches down the shaft and travel throughout the toy.
    • Discreet sound
    • Easy to use
    • Multiple settings

Care and Maintenance

Nagi is pretty easy to care for. After removing the batteries, you can wash it with antibacterial soap, use a toy wipe or cleanser, or a 10%/90% bleach-water solution. Let it air dry before storing it. You can store it in your toy box, underwear drawer, or keep it in the original box.

Because Nagi is silicone, I would recommend using water based lubricants with it.
    • Easy to clean
    • Easy to store


The packaging is a lovely over sized white cardboard box. It may too big for storage, but would make a nice gift. The instruction booklet was pretty basic, telling you how to care for your new toy and so on. Most of it was in German.

I normally don't keep the packages due to lack of space, so mine was tossed in the recycling bin.
    • Discreet looking packaging
    • Recyclable
    • Would make a nice gift


I love my Nagi.

The octopus design really makes this pretty standard vibrator stand out in my animal and sea life themed toy collection. I love that it is made from a soft silicone rather than a hard plastic like most traditional vibrators. The vibrations are too buzzy for using on my clit, but work nicely for anal play. I have to admit that I use this more as a dildo than a vibrator because of the blunt tip and gradually thickening shaft.

It isn't too thick or too thin. I don't really have any complaints about it. It would have scored a little higher if it was rechargeable or if the octopus had light up eyes! All in all, I have to say that I recommend the Nagi by SinFive.
Follow-up commentary
I'll have to admit that I don't use my Nagi as often as I used to. The silicone feels amazing and the vibrations are decent, but the lack of texture is starting to make it a little boring since it is mainly used as a dildo.

It may end up being retired to the toy box soon.

    Thanks for the review. I'd be able to ignore this vibe if it wasn't for the darn octopus. Steampunk indeed.
  • Airen Wolf
    I kinda like this line as well even if it doesn't have lots of bells and whistles and it's really expensive. It's still quite nice.

    @Petite Valentine - I love the octopus! That and the sexy look of it. It didn't come off as a girly sex toy at all. I needed it in my collection.
  • SneakersAndPearls
    Thanks for the review! I have to agree with Petite Valentine: there's something awesome about the octopus. Without it, I wouldn't even consider it.

    Oh ocotopuses! Can you believe that I got a tattoo of a girl getting her head devoured by an octopus before I even knew what he tai or steam punk was? Still a sucker for an octopus though!

  • amenti

    Thank you for your helpful review! I love the lil octopus on it, but I don't see how this is really steam punk. Maybe if it came in metalic colors or something?
