The GRAV Quartz Control Tower Banger Set 14mm 45 features an elongated quartz cylinder welded to a dish base, providing ample surface area for inserts like pearls and pillars. Three directionally cut air intakes promote airflow and help inserts spin inside the bucket for thorough vaporization. A bottom-loading intake makes placing concentrates easier and safer, while fully fused welds and an extended joint keep heat away from your rig. The set includes one 20mm quartz marble and one terp pillar insert, and uses a 14mm 45-degree male joint for use with angled-neck rigs.

My friend recommended this and I haven’t had any issues. It’s better than similar ones I’ve tried.
The built quality is good, which is why I love it, and it’s good value for money, and I appreciate the smooth finishing and the size.
For the price, the features work well. It’s a quality piece.
