## Customer Reviews

### ⭐⭐⭐⭐⭐ Great buy
*by I***A on 8 February 2016*

I always buy Oust. For me it is the best descaler that I have tried. Other brands tend to leave some limescale in my kettle and I have to do it twice. Oust is great with the first time- you can actually see limescale disappearing. Also as it comes in a handy bottle, it lasts longer and is cheaper in long run compared to buying others in sachets. Great buy.

*by M***W on 24 October 2014*

Not as fizzy as you'd expect or the bottle leads you to believe. if it's the fizz that does the biz, then that will explain it's performance. It's OK but not brilliant. Will probably be OK if you catch your kettle etc early and do it regularly. Doesn't cope with scale that's already there.

### ⭐ DID NOT SEEM TO BE VERY EFFECTIVE IN MY CASE.
*by A***. on 9 March 2016*

I don't have particularly hard water so not a lot of lime deposit in kettles. Product did not make patches of scale disappear from base of kettle. I completed process several times.Once I let it soak overnight to no effect. Repeated proceedure with very concentrated solution to no effect and even boiled the kettle (beside an open, outside door for fresh air) but still no change. Did not help my steam iron either. I have to say I found the product rather disappointing.
