Smoothly and there is no lagging, the fan is not noise and especially no hot, I must say no hot at all as we watched 2 and a half hours

the first one I got had awful crackling and static noise when plugged in from machine to external speakers or headphones

Outdoors there can be noise from the elements, so it's nice that the projector is not loud at all

, it doesn't really interfere with the playback's sound though, it becomes white noise pretty

Projector itself doesn’t make any loud noises

Its an awesome product for several reasons :- very well priced- good quality display and watching size for a budget projector- low fan noise- user friendly- very compact, comes with a customized bag which makes it travel friendly- multiple plug and play options- does not heat up after using for couple of hours

Our area is quiet so noise wasn't an issue, but it did go really loud - we lowered it due to neighbors.

The noise is a little louder than I expected, but given its compact size, portability, affordability, this is a good product.

The portable case and HDMI are useful inclusions (especially at such a low price), and the running noise of the projector is not too loud

The only issue is the noise of the fan hears too loud
