Which vibrator to buy for my on-line sub girl ?

I have a sub girl online and I want to buy her a vibrator

Please advise on the best models as I am very pleased with her and want to hear her orgasm using this. she is adorable and very curious. It blows my mind that she does not yet have a vibrator.

Everybody like the Magic Wand, but its vibrations are too intense for many people, so they temper it by using a small pillow between the vibrator and their sensitive parts.

Have a look at the ohmibod products, some of them can be controlled with a wifi or bluetooth smart phone application
