I bought this mod in the hopes that it would replace my Ali'i. It has not. The craftsmanship involved in the woodwork is amazing. The "catch cup" fell off less than a week after getting it. I contacted the manufacturer and they were nice enough to offer to replace the mod and pay for shipping. I'm not sure if that's really going to make a difference. I'm of the opinion that no matter how well you attach this juice ring it will most likely always come off. I'll post a follow up when the new mod arrives. If you have any questions please let me know!
