Thanks - that is the same batch / expiry as it has been for ages and your experience is similar regarding brand / product recognition. At sprays every 4 hours you have used a bloody lot of it and I suspect many people actually do teh shorter time interval ( assuming still advised 6 hr) as they encounter close contact in transport and coughing people etc. Cheap for short term use compared to being sick if it has worked but not sure of target market and how SPL or distributers can access them at what price point..
