Delivered filters just fine, but… to get the price they advertise on google you have to fill out a survey for some reason. Then they will email you both the code and a seemingly endless barrage of spam. Use a fake email address if you patronise the site.

*update* dropped them from 3 to 1 star. They are still sending me spam emails despite hitting unsubscribe. Based on the end of the email it seems I only unsubscribed form one type of spam. Since I can’t go lower than 1 star I’ll report to offcom if the new unsubscribe doesn’t work.
