this be pair to a mid-level , Windows 7 htpc . I work great for 6 month as long as battery be change every 3-4 week -lrb- 3 hr daily use -rrb- but start lose connection more frequently and reduce range . originally would work at 15 foot but this reduce to 5-10 foot even with fresh battery and relink the wireless connection . buy a brand name replacement mini-keyboard but recently try this one again . it seem to be work like new after a hiatus - kinda finicky .
