Pingi Dehumidifier Car And Home - Absorbs Moisture Condensation Damp Keeping Windscreens Clear - Reusable 2 x 350g - £12.10 @ Amazon

Cat litter in an old rugby sock. Does the job much better than this and fraction of the cost

These are pants, do nothing... Better off with the lil dehumidifier tubs

I had one of these and they never worked. Even microwaved it a few times, but was useless. Not voted, but cannot recommend.

I had this exact one & it literally did nothing!

Still seems expensive for the size. I've got a couple of 1kg ones I use in my campervan, paid £19 a few months ago.

Utter garbage. They don't work at all.

Worked fine for me, bought 3 previously.

1 is not enough. 1 kg is perfect.

They have worked great in car and home. Heat

Worked great in my car over past 3 winters.
Less ice on my windscreen near where they are placed proves they draw in the moisture!!

These are great. Bought these last year, and had no issues with misting up at all.
I was sceptical at first, follow the instructions and they work fine.

Are these good for bathrooms ? Hidden away
