Does the addition of item Videos make a difference to sales?

[westmoreland_steam]

I sometimes add a video clip to listings - for example, a short clip to demonstrate a working music box / metronome, but I wonder what the effect has been to other sellers?

I've seen listings with a long video and very little else, recently  and would welcome other Buyers' thoughts on the use of videos in adverts and whether the addition of a clip has improved sales etc

Any other benefits/ drawbacks would be interesting too - thank you

If nothing else it proves an item was working when you sent it, I did toy with doing 360 degree videos of an item but felt pics did it better and quicker

Yes, I did consider that too, but photos are quicker and easier, in my opinion
