If, like me, you live in a hard water area then you will try anything to help soften your water.This little gadget is under £10 at the time of review, so its well worth a try. I usually have to use double the amount of detergent in my laundry because of our hard water but it actually seems fine using a normal amount of detergent in conjunction with this Limescale Buster.Of course, I cant see whether its helping to prolong the life of my washing machine but for such a low price its certainly worth a try.

Ive definitely got a limescale issue in this old house. I dont have a dishwasher, but can use the Limescale-Buster in my washing machine. The limescale buildup is a problem in some areas, but nothing drastic. The best use for me would be to toss this most unusual household tool, as it were, in with the wash.It looks and feels like a solid block of silicone with small holes drilled through it on two sides. The idea, apparently, is that the limescale will adhere to the Limescale-Buster instead of my laundry. I usually take a pass on softeners, opting for wool balls in my dryer instead. Im hoping that, as promised, Ill be using less laundry detergent. A fascinating concept, but only time will tell if it solves the limescale issue and saves laundry detergent and fabric softener.

Our washing machine is barely new and I always make sure that it stays toptip my doing regular maintenance cleaning cycle. This is the first time I heard of this magnetic ball so I thought I would try as I am having issues of not smelling the scent of the fabric conditioner on my wash if I dont use twice the suggested dose. This is very heavy and really makes the cycle really noisy. I now have to place it in a laundry bra mesh bag to silence it a little. I have been putting half of my usual doses for detergent and fabric conditioner in my wash since this arrived and I can confirm that it actually work as my wash really smells nice. I just hate the banging noise it makes.

Never have I ever owned a product to assist my washing machine like this one, and this I'm still in the process of trying to work it out all that it does, and it does something.Well, it's heavy, much heavier than I expected it to be, and to be honest, I don't know what I was expecting.Just to mention that we live in north of England and our area has harder water, so, fingers crossed this does the trick and softens our clothes.I'd presume it would not be suitable for less than a half size load in your washing machine as it might damage the drum flying about like a fist size rock.There is definitely something inside this buster as just rubber wouldn't weigh so much nor would be so sturdy on it's own, so I guess magnet on inside, rubber on the outside.Before anythinf else or start, I've washed this product with soap, packaging isn't airtight and you don't really want to put random stuff with your clothes, regardless if they are dirty.I did my first clothes washing by filling up the drum 3/4 with adding this buster bang in the middle of it all.An occasional 'thud' was noticed when washing macine would be getting ready for a spin here and there, nothing that would damage anything.I've also added less detergent and water softener to see if that will work as mentioned on the box of this buster item.Verdict:Clothes came out soft as they would if I added the usual amount of both detergent + softener. Smell of our clothes is surprisingly good, and on touch they don't feel hard.NOTE:One slightly negative thing is that washed clothes give out a little bit of rubbery odour! Maybe or hopefully that won't continue after 2nd or 3rd wash.In regards to does it prevent or reduce limescale?! Only time will tell and I'll make sure to pop back here to edit/add that to this review and maybe increase or decrease the rating.As for now, I recommend this product.

One thing I really like: been using it for a few months and it's held up well. This has been a real help around the house.

Plus, been using it for a few months and it's held up well. My partner's parents noticed it during their last visit.

I was on the fence for a while before ordering this. Also worth mentioning: laundry feels softer without needing extra fabric softener.
