Hi Janene and the team at Colloidal, just want to say a big thankyou for your magnificent service you gave me in my hour of need. Very impressed. Bought the first bottle of dustroy about 5 months ago for my 11 year old son and he has slept great for all that time. Just in the last week or so the alergy symptoms have returned and it’s time to treat the room again. Expensive antihistamines are a thing of the past. Great product. Till next time, take care.
