I won my Water-to-Go bottle in a raffle at a charity quiz. This was a welcome surprise as I was leaving two days later to go backpacking around a 35 degree Italy. The filter system allowed me to fill up in full confidence. The bottles were particularly useful when walking around more rural areas as well as using them as palette cleanser in between Tuscan wineries!
Shortly after I took the bottles to Glastonbury where they came in as an absolute life saver when queuing for 5 hours on the hottest day of the year to get in to the festival.
I would definitively recommend these bottles, they are easy to use, the filter system allows travellers to fill up whilst knowing the water they are drinking is safe and most importantly carrying the bottles around means reducing the use of plastic by not buying bottled water from shops.
