When choosing a wand vibrator, there are several factors to consider to ensure that you find one that is right for you. Here are some things to think about:  

1. Power level: Wand vibrators are known for their strong, deep vibrations, but some models are more powerful than others. If you're looking for intense stimulation, you may want to choose a wand vibrator with a high power level.  

2. Noise level: Wand vibrators can be noisy, so if you're concerned about discretion, you may want to choose a model that is quieter or has a "whisper mode."  

3. Corded or cordless: Wand vibrators can be powered by electricity via a cord, or by rechargeable batteries. Consider which option is most convenient for you.  

4. Material: Wand vibrators are made from a variety of materials, including silicone, ABS plastic, and metal. Look for one that is made from body-safe materials that won't cause irritation or harm.  

5. Attachment heads: Some wand vibrators come with different attachment heads that can be used for different types of stimulation. Consider whether you want a wand vibrator with multiple attachment heads or just a single one.  

6. Cost: Wand vibrators can range in price from relatively affordable to quite expensive. Consider how much you are willing to spend on a sex toy.  

7. Brand reputation: Look for a reputable brand with good customer reviews and a history of producing high-quality sex toys.

Overall, it's important to choose a wand vibrator that meets your individual needs and preferences. Take the time to do your research and read reviews from other users to find a model that will provide the type of stimulation and pleasure you're looking for.
