# Common
Common quality Hyperboards have basic stats for maximum messages per day and durability (Durability), as well as a separate leveling system (level). The higher the level of a Common Hyperboard, the more messages per day it can send and the greater its durability, although its durability still differs from Hyperboards with higher rarity levels (Rarity). They may not offer the highest performance or longest lifespan, but they are a suitable option for users who do not require advanced features or heavy usage.
NFTs add an additional layer of value, as they can be collected and traded among users. Overall, this system combines engagement and community-building capabilities through messaging with the unique value and ownership features provided by NFTs.
