I was keen to try this non-bio detergent by The Lab Co mainly because it doesn't contain any harsh or nasty chemicals, so this is what I'd prefer to wash my children's clothes in. The liquid is relatively thin, unlike most other detergents I have used. The advice is to use 2 capfuls for light soiling/soft water, or 4 capfuls for hard water/heavy soiling. As we are in an area with hard water, this is the amount I have been using. The first thing I found slightly odd was it advises capfuls, but the cap it has on has a push button that allows you to squeeze the product out once open. I almost felt as though they had missed including a separate cap on the bottle that is used as a measurer. Instead, I had to unscrew the push cap (making sure it was closed) and measure four of them out. In the end, when I had a pretty good idea of how much to put in on each wash, I didn't bother measuring but instead squeezed it straight into the washing machine dispenser.Okay so onto performance, it has so far cleaned my clothes much the same as my usual detergent, so there are no problems there. The scent is very subtle, so subtle in fact that you can only just detect it, but then I don't mind that so much as if you dry your clothes outside, they always get that fresh smell anyway.I suppose my biggest gripe with this product is the price point. At £12 (time of review) for 500ml, I just think it might be out of most folks' financial reach to buy on a regular basis, especially if you are using 4 capfuls each time, like me. Obviously, I understand this is unique in the fact there are no harsh chemicals or toxins used and is mainly natural ingredients so this will make it more expensive to produce, but for me to swap from my regular detergent to this one full-time, I just don't think it is viable. I'd be tempted to purchase this to use alongside my usual detergent and save it for my kids whites and lights only.A good product and if you can afford to purchase on a regular basis, you'd be doing the planet a big favour too. 4/5
