Review: Macht genau das was es soll und riecht top
Review: Used these in my cupboard under the stairs where we had a dead rodent we couldn’t reach under the floor boards . The smell was absolutely vile. I bought one of these and within a few hours the smell was drastically reduced and gone within a day or so. Absolutely brilliant product. I have put a few of these in the bathroom and toilet and kitchen as they are so good at removing strong lingering odours They last ages too so good value for money!
