Heavy weight and noise, for this type of device I recommend back string to support other wise ears will cut for sure

Too heavy

not worth price must be around 400-500rs

No god no bad

- it is Overpriced and terribly designed.
- The fan blades are exposed on the inside and if you happen to have a thick beard or move your tongue sideways, it could get cut by the fan blades!
- The device is heavy if you wear it for a longer duration.
- There are several more expensive devices and most of them "expel" air from the maks whereby preventing fogging and removing exhaled air. This one seems to be blowing air into the mask from outside which is easily fogging up the glass


The fan...

Best for hot and humid weather to avoid soffocation dur to normal masks

Good Product 👍Makes it very easy to breathe for a good price
