Delivery is slow I am still waiting for an order I placed on 17th of July. But the one I ordered on 19th arrived about 3 weeks after I ordered. I like the glass bottle and I enjoyed the flavours. I only want a hint of flavour in my water so one tablet in around 500ml of water is perfect for me. I have found I am drinking more water and instead of buying small 500mlo bottles of bottled water I am buying one large 5l bottle. (the water here from the tap Is not drinkable so much scale) They are around 50p Plus per little cube so on the expensive side and because they take so long to arrive you have to order in bulk so its a drain on the pocket . But keeps me more hydrated.
