I have been using this for over three months now and very pleased with performance. It is very well built piece of equipment. I forgot it my pocket one day and that pant was washed and dried in full cycle. Quite surprisingly, it started working just as usual as soon as I switched it on.However there is one big con with this product. It looses connectivity with just a little bit of breeze if you are using it outdoors. This could be very annoying at times.
