We used these purification tablets for 14 days in the Himalayas. You simply need to put one tablet per litre of water and wait 10 minutes for them to dissolve. (However as the water we had was extremely cold it took longer and we waited 20 minutes). They worked great and we had no stomach problems. The only down side is the water tastes of chlorine, to combat this we added a powdered cordial (Tang). Highly recommend these tablets for the price and ease to use.

Used these in the peak district for a few days, drinking not the clearest possible water so I used a couple of extra tablets as instructed, these tablets don't give an overpowering taste of chlorine as I had imagined, just a slight taste, barely noticeable. Didn't have any problems after drinking the water, speedy delivery, would recommend.

The tablets worked really well when I used them whilst on holiday in Peru. They work quickly (within 10 minutes) and do not leave a chlorine aftertaste either. They are best used in 1 litre of water though so make sure you have a water bottle large enough as the tablets are too small to enable you to cut them in half. Also they cannot be used with metal water bottles so make sure you have a plastic bottle available. Great product at a great price!

I bought these for going to South America as I was planning on trekking. Couldn't understand how some Cl based water purification tablets could cost so much given the relatively low commercial cost of Cl so I bought these tablets as they were the best value. Having used them for 3 months in South America I can report that I suffered from no water borne infections either from my sterilised drinking water or from my Camelbak which I disinfected irregularly with these tablets. While this does not represent a conclusive field study or analysis of the tablets; nor does it scientifically confirm efficacy, I would still regard it as one positive result and I would personally consider using the tablets again.

The tablets do noticeably change the taste of the water but this is not unpalatable. Furthermore, the taste appeared to improve as the time from sterilisation increased. The tablets do not noticeably change the colour of the water and they dissolve completely so there should be no particulate contamination left in your water unless it was already present in the container or the water itself.

I've tried the tablets during a hike in the belgian Ardennes and they worked wonderful.
I didn't get sick after drinking the treated water.
The only side effect is that the water tastes a bit like chlorine but it isn't problematic.

Bought these tiny tablets to take hiking in the Lake District - do the job but leave a slight chemically taste behind (as mentioned in other reviews), so we took one of those super concentrated 'Robinsons* squash'd' mini squash bottles and it tastes fine.

*other squash manufacturers are available...

I travelled through Central America with these tablets and really put them to use. They seem to work perfectly. I even tried them out on river water. If you are using the prescribed dose, the water tastes like swimming pool water. That's a slight downside, but I guess considering the pice you cannot complain. Another advantage is that the tablets are super light (always carried some in my wallet while hiking, just in case) and that they work within 10 min (I don't like waiting for an hour). I would definitely buy these again.
