I have looked and looked for a make-up mirror with at least 10 x magnification.  I didn't want one that is battery operated because the light is not bright enough for me.  This is USB rechargeable and the brightness level of the light is very good.  Another exceptionable feature is that it folds and fits into a very nice case making it easy for travel.  This is the first time I've had a decent make up mirror for traveling.  Well worth the price.
