Not a review per se. The WHO GUIDELINES SAY ABOVE 70% for the safest and most effective results, however soap and warm water are the preferred these should only be used if soap and water isn't available. The price is inflated, all companies have inflated prices to profit. I purchased before any viruses became a pandemic because my wife uses them at work. I purchased a 24 box of Purcell with several hanging retractable belt clips for £19.99 from Amazon less than a quid each. The same ones when available are now £50 some stores are selling at £20 a 80ml bottle. All stores are doing it. To say they aren't you are not going anyone. When this is over there will be a vast surplus and the prices will reduce to near nothing to get rid.
