Handle your Weo Bottle with care. It is made of metal, glass, and plastic and has sensitive electronic components inside. It is best to use the Weo Bottle with a protective sleeve (sold separately on our website). The Weo Bottle or its integrated module (“Module”) can be damaged if dropped, burned, punctured, or crushed, or if the inside of the Module comes in contact with liquid. If the inside of the Module gets wet, do not attempt to dry it using an external heat source. If you suspect damage to the Weo Bottle or the Module, discontinue use, as it may cause overheating or injury. Do not use the Weo Bottle with cracked glass, as it may cause injury. 

Your Weo Bottle is designed to work best in ambient temperatures between 32° and 95° F (0° and 35° C), and should be stored between ambient temperatures of 60° and 80° F (16° and 26° C). Do not expose your Weo Bottle to temperatures above 113° F (45° C), as this may damage the Weo Bottle, overheat the battery, or pose a risk of fire. Keep your Weo Bottle away from heat sources and out of direct sunlight. Never leave the Weo Bottle in a hot car.

Use caution when using the device while walking or moving. Always be aware of your surroundings to avoid injury to yourself or others. 


Do not attempt to repair your Weo Bottle yourself. Disassembling the device may damage it or cause injury to you.
