Simply put this is a great cooling stem I use regularly instead of the plastic cooling unit on the OG Mighty or Crafty+. Cleans easy in alcohol or milk. Well worth the purchase.

It's worth $20 , it's more enjoyable to use than the default piece, sturdy and locks into place.

Ordered the long stem a little while back to replace my mighty+ cu. Loved it and eventually paired it with a whip + water bong. I like using it over the original cu because it’s easier to clean and deal with. Unfortunately I’m clumsy and broke it, so I ordered the short stem. Both are great, I prefer the short just because of how my setup is. I would go with the long stem if you want more cooling.

Worth the money. I love this stem and this company has great, prompt customer service :D
