From a user point of view, my Swytch conversion went far beyond my expectations - technically brilliant! (except for a cantankerous control unit which, give full credit, the Customer Support service has been most helpful with.) So why not give 5 stars? Simple. I just cannot forget Swytch's abominable, customer unfriendly marketing system, which if the company is to survive competition, must change! It may have been fine to leverage "other peoples' money" as a startup with little comparable competition and a brilliant product technically. But now, when technically viable (and cheaper) competition with a customer friendly sales interface has arrived, to expect customers to remain "loyal" to Swytch, to make a heavy financial commitment without even being told the final price of the product, and then to repeatedly place them under pressure to sign up (or lose undefined benefits) is just plain misplaced market optimism. When I (reluctantly) signed up without knowing the details, I ONLY did it because (then) I wanted the technology and there was no obvious viable alternative, so I did it, but not without resentment. I would NOT do it now. Guys, you need a new marketing plan, otherwise undoubtedly in the long term you will not survive. (My authority for such a statement? I am a retired business and management consultant with 23 years successful experience advising industry.)
