The Only One HMD, heat management device, from Aladin Shisha, is an awesome device that simplifies your setup and needs just one charcoal.
You can enjoy the flavor of your tobacco for up to 90 minutes.
Inside the Only One, you will see 3 spikes, on which you will place your charcoal. Thanks to the spikes, the charcoal doesn't get a black spot, because it gets air from all sides.

The device comes with a nice handle that helps you to lift the lid of the attachment easily without burning yourself.

The Only One is also ideal if you want to smoke outside, as the lid works as a wind cover.

Of course, the Only One also fits conventional clay bowls and many other popular models.
Always pay attention to the diameter of the bowl, so the attachment fits well.

Total height: approx. 5.3cm
Height without lid: approx. 2,5cm
Diameter: approx. 7cm
Diameter bottom groove: approx. 4.6cm
