Our primary reason for ditching Slingshot for Orcon was connection loss. This was extremely common - light goes out on modem, can't get into internet, call Slingshot and hear an automated 'apologies for technical issues' message. In half a year with Orcon, there has only been one loss.
But now some sling shot plans look like really good value, and their off peak scheme is great. Thinking of switching back, but not if the connection is to be unstable. So slingshot customers, what's it like now?
