There is no doubt there is some seriously cool technology on display at the Consumer Electronics Show in Las Vegas, but one product is proving that the simplest things are often the best.

Liquipel is a preventative coating for smartphones and other mobile devices, which offers protection from water damage in everyday scenarios like using your device in the rain or dropping it in the sink.

President of Liquipel, Kevin Bacon (a different one), told Paul Spain of the NZ Tech Podcast that while the product has demonstrated some extraordinary water resistance, he still wouldn’t recommend taking your iPhone in the pool.

"Our main concern when we started the company was to cover most of the scenarios under which people water damage their devices,” Bacon says.

"Through our research and through our performance with our coating we’ve come to find that we can cover about 90% of the situations under which people water damage their electronics, so accidents like dropping it in the sink, puddles, rain, all these other situations under which your device would normally become damaged, Liquipel is able to save it.”

The coating costs US$59, and while the company is concentrating on the US market at the moment they are happy to coat products from overseas, provided the owner is willing to pay the shipping costs.
