The effects are good, but almost every cartridge I’ve had from BOUTIQ brand eventually leaks. They work fine at first, and the vapor production is good at slightly higher voltage, but that’s usually when they start leaking. With continued use or heat-up, the leaking only gets worse. Some have leaked so badly that the oil completely overflowed and even ruined my battery. At this point, even if these cartridges were free, I honestly wouldn’t use them because the leaking is that bad. The effects are good, but the cartridge hardware definitely needs improvement.

Quick service. Staffs were friendly and kind
