Durability, ease of use, value.
The most practical easy device for its purpose I can imagine! It’s unbreakable, no fooling with screens, doesn’t get hot, is easy to clean, lightweight, and is very ergonomic. The lid is such a fabulous idea, and now you have an attached lid! This works to transport everything without emptying the bowl (just the water). It also will contain the smoke for discretion and conservation of contents. The more I use it, the more I like it.
Great idea and materials. One poor design flaw: bowl is positioned too high up, so when lighting heat is very close to your face.
When was the last time you broke your silicone bong? Feel me? Super slick, easy to clean and easy to find in the middle of the night. Grab one, now!
