Rated 5 out of 5 by from mazers Amazing! I use this to refill plastic unit I have in the wardrobe and it's totally solved the mildew problems I was having. I used to use those pesky 99p plastic ones that you can't refill and getting a refillable unit and this refill crystals is so much more cost effective and much less waste. It's daft how such a simple product can make me so happy but it really does!

Rated 5 out of 5 by from Works like a dream :-) I have moisture traps all over my bedroom - inside and on top of wardrobes and 2 by my toilet water tank. This is the best price I have found for these bags. I bought 3 bags and got them delivered. They arrived well packed and quickly.

Rated 5 out of 5 by from Best value seen Used these crystals several times now. Base kit for caravan then expanded to more boxes in cooler or unheated rooms. Forget costly dehumidifiers and the running expense!? These dudes grab water 24/7 oveř a few months. Even set smaller trays in clothes cupboards in winter months

Rated 5 out of 5 by from Great value alternative Using these crystals as a refill for standard (single use) dehumidifiers is a great saving! Also, the Screwfix price is better than any other supplier I've found. Well done Screwfix!
