Pulsar GiGi H2O 510 Battery with Water Pipe Adapter
Ergonomics and quality are very good for price. My favorite.
Followed the instructions to the letter. Cartridges would straight up leak out of the bottom of the battery if using the pipe attachment. Eventually cracked where the cartridge threads in as well. Overall a really bad experience, though I love the idea.
Bought two. One quit could hear a rattle inside.
Figured maybe it got dropped. Few days later second one quits. Same issue. I know I didn't damage the second one. So disappointing after my first one I bought..then lost had lasted for years with out issue. No more pulsar products for me
