So I got this in just yesterday and I've already tried it several times happily.

Feel: The silicone of the Siri is amazingly soft, smooth and velvety. I can't really give a common example for you to compare it to, but it's very pleasurable.

Size: The 1:1 ratio is accurate, but it does seem smaller in real life. If you hold it in your hand and close your hand around it, your hand can almost encase it. There will be a 1 centimeter space between your fingertips and the heel of your hand (width of a pencil if you're unfamiliar). It would be easy to stick it on your jeans pocket. It's a little larger/bulkier than a Maybelline 'Baby Lips' lipstick.

Looks/Interface: It's very elegant and cute, and right out of the box I loved my Siri. It has the same sort of elegance as the Apple products do. They're sleek, smooth and simple. The button interface is super easy to learn too. Up/down cycles you through 6 different patterns. +/- turns up the vibrations, or down. Press and hold the minus for off. Press and hold the plus for on. Hold both the plus and minus to lock and unlock. Simple, right?

Sanitation: Be careful! It's not waterproof, so I don't even get water on any of the white part. On the colored portion I just used warm water and hand soap. BUT, be careful that the soap does not contain silicone! Silicone products, especially lube, will make it have a sticky/tacky feeling that is PERMANENT.

Noise/Sensation: Siri is very quiet. On full power, I doubt someone could hear it past a closed door and under the covers, but having the stereo up never hurt anybody. Out of the box, just playing with it, going through all the cycles and messing with the interface, my hand went numb just holding it. This is great because I love strong vibrations. Setting it on a table, she will move on her own from the power of the motor.

Other Observations: Siri is easy to use but with the minus button, if you're trying to turn Siri down, it's possible to hit the button long enough to turn her off.

So I've tried it three times already, and I have to say that while my hand went numb playing with it, I didn't get off super easily with Siri. BUT, I have a Pipedream Bullet vibrator, and it's strong enough to get me off in a minute or less. This isn't always the best since with that one (I only use it on my clit), I get off once and THAT'S IT. I can't get aroused anymore for the night, I can't penetrate myself with anything, and the orgasms border on painful and overwhelming.

Siri leaves more room for extended play which, to me, is fantastic because I don't always want to be totally drained in less that 10 minutes of play. I do get off with her fairly easily and I'm ready for more or to be done for the day, depending my mood, easily with her. She's versatile and fits my moods. I'm pleased.

Also, her shape is great; just close your legs with her nestled in her place and you're hands-free to do other things. In my opinion (I haven't tried yet), she would be great to pair up with another toy like a dildo or anal play. I can't see her getting in the way of sex with a partner either. She's just too small for that.

Do bear in mind that she is quite small, and as a larger lady, you might have to bury her further or press harder. This is just a thought.
