I've used them for months now, and I had no problems! Their interface is very easy to navigate and not to mention, their prices are cheap. :) In total, I have 6 domains hosted with Omnis.

In my opinion, Omnis > GoDaddy

I have not hosted with thems, but two domains regostered with them and have a very clean interfase and profesiona emails.

Thumbs up for Omnis too.

I have no experience with Omnis, but according to their website they seem to be a reputable company. Thanks for your review.
