I keep receiving their emails almost on a daily basis. It says there "If you wish not to receive any more information and special offers from I.R.I.S. simply send an email to newsletter@irislink.com with the word "remove" as subject." I have followed this simple instruction several times by now, but always get "Delivery has timed out and failed". So let me tell them publicly: I am not going to buy your product at its present quality, and with the bad support reported here. Please leave me alone.
