Just purchased the Osmio Sanser Sanitizer spray 500ml unit. Can't believe is was so cheap and I got a £10:00 discount voucher.... What a result I have been using this type of disinfectant made from water and sea salt for about a year. Found out about the solution from a medical journal but could not find a supplier in the UK for this equipment. Ended up purchasing from the USA. Cost me a fortune!!! Then the next month this device was on sale for a fraction of the price I had to pay for my original USA device. So straight away I purchased it (I love a bargain). Easy to use, add water, salt and plug in....... The thing I like about is the mist delivery system. When you spray you sort of pump and the solution come out in a fine mist, which is really good for covering surfaces. Its not a wet mess it a fine mist that evaporates as it disinfects. There is a negative to it. Which is nothing really!!! When use use it on dark surfaces constantly, you get a shimmer to the surface, which I think is the salt converting back to its original for. Nothing you can't handle with a simple wipe with a cloth and warm water. Buy it.......... its cheaper to make your own than to buy this solution from a chemist/Shop
