Using the Lelo Ina Wave 2 is a breeze. First, make sure it's fully charged. You can do this by plugging it into a USB port for about 2 hours. Once charged, turn it on using the 5 - button interface. You can then choose from the 12 different vibration modes to find the one that suits you best. When using it, apply some water - based lubricant for a more comfortable experience. The vibrator is 100% waterproof, so you can use it in the bath or shower too. Just rinse it with warm water and mild soap after use, and dry it thoroughly with a soft cloth. Store it in a cool, dry place away from direct sunlight. Remember, this product is for personal use only, so don't share it with others. Also, avoid using oil - based lubricants as they can damage the silicone material. Enjoy your pleasure journey with the Lelo Ina Wave 2!
