The best thing about inero is that they have very good customer service, which makes it easy for them when you need any help or assistance with your server setup process! You can also get great prices from their hosting services as well if needed (which I highly recommend).
There are not many things i dislike at this point but maybe some other clients don't like how fast everything gets done once we sign up? It's hard sometimes because our team works really quickly so there may be times where an order doesn't go through right away due too us being busy working instead getting orders processed immediately after signing-up etc.. But overall its been pretty smooth sailing since starting using incaro almost 3 years ago now :).
