It's about aggregated reviews. If a product is 4.5 stars and above and has hundreds or even thousands of reviews then the general likelihood is that its good. If it has 25 reviews and most are paid for with an included voucher or free product then its probably not great quality. However good luck with it and let us know how it goes!Yep will see how it goes, I'm not too concerned about the minimalist style, I know some of the reviews are vine but they do seem genuine to me, to be honest all the straps even the Kiwi get some one star, so its probably a bit of a lottery to get one you are happy with. Will come back with a bit of feedback when I get it on.
