I had a seamless experience getting my UAE visa through Emirates e visa online. I filled a very simple form with only the very necessary details. Then the payment was also smooth through my credit card.
I actually did a small mistake and their representative was quick to identify and reached out to me and corrected it.
Bonus, I applied for a normal service which should take 3-4 days but I actually received my visa in less than 4 hours. Definitely going with them for any future visa requirements for emirates.
