If you're considering the G90, it might be better to opt for the 891 instead. They have similar sizes, and the 891 offers 800 watts of power plus excellent community support, which is sufficient for treating fever. The X6100 is suitable for those who need a portable device for outdoor activities or long-distance travel, or for frequent business trips. However, if these needs aren't essential, there's no need to buy the X6100.
