of Clark reviewed on 25/05/2017

Doesn't work on my TV, the product doesn't work on any adapters, the instruction manual is weak and unclear. A complete waste of time and money. Hifi Tower return registration page is 'unsecured' so cant return item, customer services is closed for national holiday so can't call them. Will not buy from them again, and will be reporting them to trading standards for selling products with false advertising, product isnt compatable and customer service and website is not customer friendly.
