I have used many carbon filters, and this one is among the best for its design and quality. Saves tons of time and effort cleaning glass.
Excellent. Smoother smoking.
Its too long so it makes the stem of the water pipe stick out too far...
They called to double check I made the purchase after seeing my billing and shipping addresses were different. If that's not a sign of a company who goes the extra mile for customer service, I'm not sure what is. Great product as well.
