The Grace Glass OG pre-cooler with built-in showerhead percolator promises maximum smoke reduction for all glass bongs with an 18.8mm cut. The additional effect is particularly noticeable if the smoke has already passed through a perc in the bong beforehand. The precooler is 15cm tall and has a glass wall thickness of 5mm. So an appealing level of break resistance is also provided.

Breaks easily After purchasing this precooler, the joint on the top started cracking within the first week. After asking for a replacement, which i received within a week, the second one broke again. This was entirely my own fault, as I accidentally dropped it. It wasn’t that high though, about 20cm, and the inner black diffuser broke. It has great functionality, and customer support was great, but the inner perc does see to be really thin and fragile.
