Everything about this toy is exceptional. First of all, the Siri is crafted by the Swedish adult toy company Lelo, which is an emerging gold standard in the sex-toy industry. They bring luxury design, medical grade materials and guaranteed technology to their complete line of toys and this external vibrator is, for me, their crowning achievement. With all the simplicity of a one-speed bullet, and intelligence of a cellphone, this is the Rolls Royce of external, clitoral stimulators.

The silicone that splits the toy in two, (and is intended for direct body contact) is not powered by a regular motor like most bullets, but rather wrapped with a smartly designed silicone that literally offers a network of webbed sensors that execute the vibration. The 8 speed range goes from a gentle patter to a roaring roll and within each is the ability to switch into one of the 4 patterns: slow pulsations, quick pulsations, slow crescendo, quick crescendo. The toy also has a randomized function where it starts and stops unpredictably and goes through patterns- I found this inconsistency in rhythm and speed particularly pleasing and very similar to human interaction...

Refrain from using this toy with a silicone lube- over time silicone can break down another silicone on a molecular level- and chances are whatever lube you have at home doesn't have the exact makeup of Lelo silicone. Try to use a water-based, glycerin-free, paraben-free lubricant if you need to, however, the silky feel of this silicone tip, probably won't require it.

The keypad is similar to a remote control and since the toy fits in the palm of your hand, all buttons are easily accessed during use. I like to use my external vibrators with an addition internal toy, and with practice, one can memorize the button placement and seamlessly use the toy single-handedly.

Using this toy with a partner, particularly during intercourse is spectacular. Due to the petite size and slight curve, it can wedge between partners. After use the toy's surface is easy to clean and even if you care for your Siri irregularly, it's quality silicone won't become porous and it won't attract dust, dirt, etc.

This is a rechargeable toy and it's power source is similar to a cell-phone charger. Depending on use and lifestyle you should be able to use the toy without recharging it anywhere from 1-3 months. Like all Lelo products this toy has a year warranty, so if anything happens the company will take the toy back and replace it no questions asked. If the toy expires or is defective after the 1 year warranty, the company will still accept the old toy and give you 50% of your money back to put toward another toy.
