Works well for a small out of the way htpc controller . not as easy to type on as my cell phone , but still work good . sometimes it seem like my finger dont hit what I need they to , but that a issue with big hand more than the controller . the integrate laser be good for pet entertainment more than presentation as I dont normally do many presentation in my living room ; -rrb- battery life be good , and range be also good , I havent have any issue with either .
