"...wanted to replace battery for my cartridges which I spent fortune and stop working after few days. Thank god I found Blue Nile. They recommended me the 4D battery with variable voltage, let me tell you, it's a charm. $15 only. Anyone who need battery for cartridges should definitely go for the 4D..."

"I'm in love with 4th dimension products! Was introduced to this brand at the smoking shop in west village. I purchased the 4d water pipe beaker style and their mat black grinder. Functional, elegant, and above all amazing quality. Water pipe looks amazing and works amazing. Nice and smooth hits. The glass is thick and solid. The grinder grinds evenly into a perfect blend and doesn't get sticky and gunky. This is the good stuff. Love it!!"
