Siri is designed to stimulate the clitoris and vulva, but can also be used on the nipples, anus, or other external areas. It would work well to stimulate the clit during partner sex, and can be used alone or with another toy during masturbation. It is very quiet which is great for anyone who lives with other people, like I do. Siri is not waterproof, so you can't take it in the tub or shower. It would be a good toy for traveling since it is small, quiet, and discreet and can be locked so that it won't turn on in your bag.

The body of the toy is made from shiny white, ABS plastic. The underside and tip are covered with a thin layer of silicone in either pink, red, or purple. It is not squishy or flexible due to the hard plastic underneath. The silicone is smooth, matte and silky with a slight drag. Siri is non-porous and does not contain phthalates or latex.

Siri is palm-sized, 3 3/4" long and 1 3/4" wide. It is ergonomic and fits nicely into the hand, and (more importantly) onto the vulva. It is shaped like an oval with a slightly pointed tip and a rounded ridge on the bottom. You can use the tip for pinpoint stimulation, or lie the toy flat against the vulva so that the ridge rests on the clit while the sides of the toy stimulate the labia. It is small and doesn't have a phallic shape, so it is discreet and easy to hide.

Siri has 8 speeds and 6 vibration patterns:
1. Steady vibration
2. Slow pulsing
3. Fast pulsing
4. Escalating from low to high
5. Escalating from low to high, then back to low
6. Random

You can adjust the speed for each pattern. The vibrations are low-pitched and throbby. They are strongest in the tip, but travel pretty strongly down the short length of the toy.

The controls are simple to use, but you have to press the buttons quite firmly. There are 4 buttons, a + and - sign and an up and down arrow. Holding the + sign turns the toy on and increases the vibrations. The - sign decreases the vibrations, and after the lowest level is reached, turns the toy off. The arrows take you through the vibration patterns. They are not in a loop, so you can't use the up arrow to go from the last pattern back to the first one. Holding all 4 buttons down for 5 seconds will lock or unlock the controls.

This is a rechargeable vibrator and according to Lelo a 2 hour charge will give you up to 4 hours of use. It lasts me about 3 sessions on the highest, constant setting. If you use a lower setting it will last longer. The buttons flash white to indicate that the toy is charging, and stay lit when it is fully charged. They flash red when the battery is about to die. Lelo advises waiting until the battery is dead before recharging. Siri can be turned on while the charger is plugged in, but it should not be used this way because it can damage the battery.

Only water based lubes should be used with this vibrator, since silicone lubes can react with silcione toys.

The charging port has no cover, so you have to be careful when cleaning it so no water gets inside. Use a toy cleaning wipe, or a damp washcloth with antibacterial soap.

Lelo packaging is classy and discreet. There is an outer box in the same colour as your toy, with a black box inside. The toy is encased in a clear plastic bubble surrounded by a flat piece of black cardboard that is meant to be hung up at a store. It comes with instructions, a warranty, and a white satin pouch that can be used to store both the Siri and it's charger.

I like Siri, but it's not as stimulating as I hoped it would be. It feels pretty strong in my hand, so I'm not sure whether it's a lack of power, or if it's just not the right type of vibration for my body. The Siri does make me orgasm, but it takes longer than I would like and I have to rub it back and forth across my clit to get more stimulation. I like to use it with my partner since it's quiet and can be used while we're having sex, but it wasn't able to knock the Form 2 out of it's spot as my go-to clit vibe.
