Pack of 10 x 500ml Interior Dehumidifiers with Fast Acting Crystals – Ideal for Use Around The Home, Office, Caravans and Small Spaces - Helps Prevent Damp, Mildew, Mould and Condensation

Be patient! It may takes 7-10 days to work. On the first few days nothing happened. After that we noticed the little balls stuck together. Another couple of days and we noticed few drops inside the container. Another few and more and more moisture been collected, just happened as on the discription on this things. My window had a waterfall on it every day. Now, only a little. I put them all around the house, all together 5 windows. Most of them had same amount of water on it every day. Now all dry! I also started a good habit to open the window every day, but some days I forget, but still, my windows are dry. I cleaned all the terrible moulds from the windows and from the wall, hope it's not coming back.My suggestion: if you want to use this, you have to wait 7 days, before it's start to work so be patient. Check it often, and before it gets full, open another one, put it next to it, just to make sure you not get condensation back on your windows.I think, mine will last for another month at least in the wettest room. We usually dry our cloths in here, but with open windows, and 2 person sleeping in the room. Other containers still only have little water in, at least they last 3 times longer according the amount of water I see.

Does exactly what it says. It has resolved condensation mould in a cold, rarely used en suite bathroom (even though it says it’s not recommended for use in bathrooms), a utility room and an unused downstairs toilet. It has also removed odour problem from a shower drain. Obviously has a short life in a bathroom but worth the money for the problems it resolves.

They do what they say they will very well. Not the best look but on top of a wardrobe ok

This product is wonderfully easy to use I would go as far as to say foolproof, I own an old jaguar with all the inherent faults the main one being virtual ponds in the boot resulting in many of them being scrapped. Thanks to this product I now own a very dry old jag, virtually unheard of! Therefore I do not hesitate to give a 5 star rating for this.

Easy to use. Not sure how well they will work as they're down now for the winter in my caravan. Had something very similar last year and they worked really well.

We used the same product last year to help with damp accumulation in static caravan. They worked very well. Not actually used this new pack yet, but I'm sure they will be just as good.

The crystals become solid very quickly not allowing the water to drip through into the container belowNot as effective as others I have bought

I’ve used this product before in my mobile home and found it very good in keeping down the damp in the winter, when it’s been closed up for at least 5 months.
