Is this better than the Marpac Dohm-DS Dual Speed Sound Conditioner? (it's currently the #1 best seller in sound machines on amazon). Why yes/Why no?

I had an original Marpac 330 sound machine which was a great machine and lasted for 30 years. Ten years ago I tried to replace it and the new machines had a very annoying sound loop. I called Marpac, they were so nice, sending me machines but they all had that problem. I tried a Sound Dohm at Bed Bath and Beyond and it just didn't have the volume of their older machine. Wish they still made that version.

Anyone use a real fan first and then switched to this? Why did you switch ? I use 10" solder exhaust fan.

I like this better than a real fan because: You have 10 different fan "frequencies" to choose from. Can experiment to see what masks the annoying sound you are trying to cover up....Also has 10 different "white noise" frequencies too...Can adjust volume quite a bit more than with a fan...and is also good if you need big wooshing fan sound to cover up a noise, but don't always want a fan blowing air around. I hope this helps! I use it in an office environment- it has been great. (Before I was using fan - sometimes had to use 2...got very windy.)

How is this any better than just hooking a speaker up to an iPod or phone and playing white noise audio files? Or just using an actual fan?

I currently use my Apple Homepod to play white noise in our bedroom. Apple Music has a number of white noise tracks available. I use a track off an album by "Dr. White Noise", I made a "White Noise" playlist on iTunes, I copied the track ("Soft Dehumidifier Fan Delight") 12 times so it will play for 12 hours (the track is 1 hour long). It works and sounds great. You could certainly use speakers hooked up to your phone or iPod to accomplish the same thing. However, if you needed to purchase speakers to use with the phone/iPod, it seems like you might as well get this unless you want to use the speakers for music, etc. in the bedroom. This device would certainly be easier to use than hooking up speakers each night, plus it would likely take up less space. That said, I am thinking about trying this device too as we could use it in our Airstream travel trailer when we are traveling.

Can it run on batteries? If so, for how long? Also has anyone used it overseas?

Considering the small amount of power it uses (2.5 W) it should be possible to run it off of any device that can steadily supply 5V at 500 mA DC. As such, if you can find a battery pack that can output 5V @ 500 mA and has a USB socket on it the Lectrofan should run off of it no problem. As for how long it can run off of a battery pack, it would depend on the rating of the battery pack being used.
