Cambodia e-visa

Yes,I have!It is what it says-we uploaded our photos,filled in the form,paid our $25 each($5 handling/processing) and I had it in my inbox the next day!Printed off the required 2 copies,sent a copy to another email address I have(just in case!) and entered Cambodia relatively hassle free!We didn't have to pay anything extra,weren't forced to pay in baht and off we went!
The only down-side is, although it didn't affect us,that you can't use it at every border crossing.But as entered through Trat/Koh Kong (and had it checked again in S'Ville,as we got off the boat) and left via Poipet,it was really as easy as it sounds!
Hope this helps,

I used them on my trip to Cambodia in July. Went in at PP airport and out of SR.

Very easy, no queues. Bypassed all the other tourists joining the line to pay for them on arrival. On our flight there were at least 50 others in this queue.
We walked straight past and was first to be served in the "e-visa" check point. Whole process took less than two minutes.

We did the same as #3 in at PP out at SR airports. No extra cash had to be handed over - all went like clockwork.
Scanned the photos in from the passports and did as #1 says - only difference was that all four of our visas (all done by me) came through in about 2 hours - even though the website said there may be up to a 3 day wait!
