I think my product review said it all, but if you want to to tell you again, I will. Most annoying marketing ever. You send daily email asking me to buy product and review product when I have barely had a chance to open the kits I bought - one for me, one for a family member. Your "update preferences" to get fewer messages does not work. I would unsubscribe but among the barrage you do send periodic useful tips on how to use the kit. There is no need to send me email daily, once every week or 2 really should be fine, right? Please stop.
