HypericeVenom 2 Right Shoulder - Advanced Heat + Vibration Wrap (Right Shoulder)

What is the maximum waist that Venom 2 covers?

Can you use this for the elbow area?

Anyone have any real world times on how long the battery lasts when the heat is set to level 1, level 2 and level 3? They says up to 3 hours but.....

Does this come with a manufacturers warranty? If Yes, how long is the warranty good for and what does it cover?
