* It's a misspelling: Perhaps you meant a different brand or model name. Could you double-check the spelling?
* It's a custom or niche product: The name might belong to a handmade or very specialized lighter.
* It's a fictional product: It might be a name from a book, movie, or game.
To help me understand what you're looking for, could you please provide more context? For example:
* Where did you encounter this name? (e.g., online store, advertisement, friend's recommendation)
* What do you know about the lighter? (e.g., its appearance, features, price)
Once I have more information, I can try to help you find out more about the "WEQTETJU" lighter and determine if it's worth the spark.
