The SinFive Flow is like the perfect multi-purpose tool. You can use it for just about everything.
Twisting and bending is everything with the SinFive Flow. It's super easy to do, and you can twist and bend till it suits your body. It's almost like a one-size-fits-all dildo in terms of making it find your G-spot or P-spot, reaching your clit, or both your vagina and anus.

So here's a rundown of the main uses for it:
It can be used perfectly straight like an average dildo, and if twisted, the twists in it provide nice texture. The twists can be very tight, or you can leave a little space between them so the dildo is a little wider. Heck, you can just untwist it and insert it straight, or only have it twisted at one end!
You can curve it to hit your G-spot or P-spot, or you can completely bend it so you have a handle to use. It has no flared base, so if used anally you basically have to make your own base and really bend and twist it to ensure it doesn't go all the way in. You can use it both vaginally and anally at the same time.
Depending on the size of your hands and wrists, you can put both hands through it when totally untwisted, and twist in between, so you have a make-shift restraint that you can easily get out of. This might be fun for those that just want to try out cuffs.

The other cool feature of this dildo besides being able to manipulate it so easily is being able to use a bullet with it. It comes with a pretty strong bullet, or you can use your favorite. You can fit a bullet between any of the twists to stimulate your clit, or just to make the dildo vibrate.

The box even specifies that the Flow can be used "vaginal or anal, vaginal-anal, clitoral-vaginal, vaginal-vaginal. Let your imagination run riot"

So, do as it says and use your imagination and experiment, there's bound to be something you like with all the possibilities.

The material of the SinFive Flow is amazing! It is 100% anti-microbial silicone. Yup, that's right. It's anti-bacterial, just as many soaps and hand sanitizers are, so you won't have to worry about bacteria breeding on this toy.
The Flow is latex free, hypo-allergenic, phthalates free, non-porous, and made of food-grade material silicone.

The Flow is a pretty firm silicone, but with some give when pressed (like many other silicone toys in my experience). There is quite a bit of a drag when touched also. The silicone is surrounding a metal wire, but you can't even feel it when you squeeze it.
This texture is good for anyone, it's smooth and inviting.

There was a very faint smell when I first got this, which went away with washing. It wasn't a bad smell, and I can't quite identify it. My best guess is just a silicone smell. There's not much taste to it, but the little bit there is I don't enjoy much. I didn't even taste anything till it had been in my mouth for more than a few seconds at a time.

The design of the Flow is so innovative and different. When not twisted, it's just a long oval. You can change it into any shape you'd really like though. When made into a circle, it's bigger than my face!
I love the design of it and the ability to change it into any shape you'd like. Twisted tightly or loosely, no curves or a few curves! Whatever fits your body, the possibilities of it are endless.
No matter how I twist it, the end is always round. I personally love this, but those that like a more pointy tip might not be pleased. You can twist it so the end has a bulbous head for easier G-spot stimulation as well.

The size of the Flow is so hard to specify because you can make it into just about any size you want. Untwisted and in a long oval, it measures to be 11 inches long with a 3 1/2 inch circumference. It really doesn't have much girth, but you can twist it with very loose twists to make it wider.
The length is great because can bend or curve it to make a very small insertable part, or insert the entire thing. Because the size is adjustable to how you want it, this is a good toy for anybody. The bullet is 3 inches long.

As for being discreet, I definitely think the Flow could pass for something else. If the bullet isn't in it, and it's completely untwisted, or twisted into a weird shape, it could look like some random knick knack or decoration! You could even get creative and try to make it look like something in particular and set it out.
The only thing that would stop this from being easy to travel with is the size. but if you twist it then roll it up, you can get it to be pretty small. It doesn't look like your typical dildo, so nobody would guess what it is.

What's best about the toy to me is the fact that you can change it up so much. You can contour it to fit YOU! And you can also make it a different shaped dildo depending on your mood or if you're going solo or using with a partner.
The bullet has one speed, but it is moderately strong. It's pretty buzzy which made it seem louder than it actually is to me. When placed under a blanket it doesn't even sound half as loud.

The box of the Flow suggests to wash with warm water and pH-balanced soap even though it does sterilize itself. Since it's silicone, one would think you could boil it, but I wouldn't want to risk ruining the anti-microbial properties of it so I'm going to rule boiling and a bleach solution out. Other silicone SinFive toys say in the directions or on the package that you can boil, so if you could with the Flow, then I'd assume it would say outright.

I thought this was going to be a tough one to clean, but all you really have to do is untwist it, so you have a big ring of silicone, and just wash it like that. It turned out to be quite simple.

This attracts so much lint! So, keep that in mind when choosing a place to store. I'm keeping mine in the box it came in for now, while it isn't exactly perfect for storage, it works until I get a pouch for it.
Also, it's a good idea to at least rinse it off before use because of how much lint it attracts.

This is silicone so two things: Do not store directly next to other silicone toys. And Do not use with silicone lubes. Silicone plus silicone just don't mix!

The Flow came in a grey box with pictures of different ways you can use the Flow. It suggests ways to use it, and says that while there are more ways to use the Flow, they do not assume liability for them. The only care instructions I mentioned earlier are in one sentence on the box.
Inside the box, the bullet was nicely placed, with the Flow twisted and sitting inside. You open up the front of the box to get to it. It is a cute box to be used as a gift box, but I have trouble keeping it closed. Mine even arrived opened.
This probably isn't the best box for long term storage.

I've tried the Flow in quite a few different ways, and it works pretty well. It isn't my favorite though.
If used twisted, the twists provide a lot of nice texture, and I love texture. Placing the bullet anywhere has been amazing, and it's a good bullet. This was a little awkward anally, but with more practice I think I'll get more used to it. It was easy to use for double penetration, which surprised me.
I haven't tried it yet, but I was able to shape it into what looks like a pretty good shape for a butt plug as well. I'm a little skeptic to try that at this point, and it probably wouldn't provide the "full" feeling like most plugs. I'm open to the idea down the road though, it could be fun.

This is definitely a toy I would love to use with a female partner, just because I could change it during use and keep doing new things with it to her.

I absolutely love SinFive, and this product is a really great idea.
One thing though-I've had just as much fun playing with it and shaping it as I have using it. It's a really fun toy, and sometimes it seems like more of an actual toy than a sex toy. You can sit there for hours and change it to see and try every possibility.
