Shiro 3 It’s noisy but it is written on the manual that it’s normal for it to be noisy. I tried the deflate function to the floatie but it deflates faster without this device. Inflating function definitely is good. I guess we can’t have everything.Also, it is not good to use for large floaties. It’s easier and faster to use a handpump included with the floatie set than using this device.It’s good for wheels though for specific psi.
