I have to agree with the other posters. A bong is completely worth it, but your price level is too low. I have never spent less than $50 to buy a full-sized bong, and even my bubbler cost over $50.

I would suggest you set your budget closer to $75 or higher to get a high quality glass bong that you will enjoy for years. My first purchase is still my number one bong and gets used regularly, even though it is several years old.
