The Osiris Mini RTA marks the latest addition to the Vaperz Cloud lineup, a dual coil RTA with a 25mm diameter. Its deck features four individual post holes, each measuring 2.5mm x 2.0mm, making coil installation a breeze. Additionally, it offers four separate wicking ports designed for high-wattage vaping. The ''Full Flow'' juice flow control in the Osiris allows complete customization, including locking the deck to the inner barrel. This feature ensures full control over the juice flow, preventing disassembly, which is especially useful during travel or for adjusting wicking flow based on wattage or e-liquid type. The Osiris stands out with its unique bottom-shoot airflow system, ensuring it hits the sweet spot for flavour intensity and vapour production. The Osiris Mini RTA is your go-to choice, whether you aim for dense clouds at high wattage or robust flavour at mid-range wattage.

Bits missing?

According to VaperzCloud themselves this rta DOES come with an extra separately packaged bubble glass. Yet Rainbow Vapes did not send one!? And I DID contact them and this is the first time customer service has let me down! Just mentioning the price and that's why!?!
Whatever the price, if something is meant to be sold with accessories, they SHOULD BE included!
