I've been using the Oasis Blade Version 2 for about 2 months now. While the wind power is noticeably better compared to Version 1, it still isn't strong enough to cool down a room effectively. As a result, I often have to use the maximum speed setting (level 6). However, at this speed, the fan produces an irritating noise. I've had tech support visit twice, and they confirmed that this is the normal sound. Unfortunately, as a light sleeper, this noise really disrupts my sleep. If you're looking for a fan that's truly quiet, this one may not be the best option.
