I bought the same one as you Watersiren, when it was a TSV last November. Mine has been fine thus far, but I have always felt that QVC's technology products (if this toothbrush comes under that category?!) are more apt to break down simply because they sell in such volumes that there is a greater chance that things are not going to be fabulously made. Or maybe I've just been unlucky as every bit of kit I've bought from them - other than the toothbrush - has ceased to work pretty quickly :dull: If you've had the product for less than a year they should replace it without question, but my understanding is that legally a consumer has the right to a reasonable life of use from a product. What constitutes a reasonable lifespan in this context is open to debate of course, but I do know of cases where people have had, for instance, a washing machine replaced a year or two outside of the initial one year guarantee that is offered with most electrical goods as they have successfully argued that such a product should be expected to perform for longer than twelve months. Obviously that's a bigger item, easier to argue that it's not the kind of thing one expects to re-purchase annually, but still...in my experience although some of QVC products have been a bit wonky CS have always replaced/refunded with very little argument.
HTH :up:
