Measuring 50mm x 27.3mm x 81mm, the SMONO 3.4 is the handiest of the Smono range. Its compact design allows it to be taken on trips without sacrificing much storage space. The mouthpiece is molded from hygienic glass and the body has a soft-touch surface that won't show fingerprints. Unique for this size is its advanced convection heating system. Here, the herb itself is not heated, but the pre-heated air flows through the material. With this gentle system, softer steam is produced and the material is used more efficiently. The operation of the SMONO 3.4 is deliberately simple with only 3 buttons. Lovely detailed drawings have been included in the comprehensive instructions to clearly explain how it works. The SMONO 3.4 has a high-quality glass mouthpiece with an integrated glass cylinder. Two colored LEDs signal inside the viewing window when the perfect vaporization temperature has been reached. For cleaning, the mouthpiece is easy to disassemble.
