    "Love it...Not bad....Best idea to fight constant power flickering from the unreliable service from Florida Power & Light, I have been dealing with power company about constant power flickering, and as always they won, so my solution was to purchase three of these Battery Backup System, and now I eve have some time to keep enjoying my electronic devices, even with power failures....I'm using this power backup device to protect a front projection projector from lamp damage from a power failure, Without this, loss of power would leave the lamp subject to damage from the heat of the lamp not being cooled in the event of an AC power failure, The lamp alone is more expensive than the Back-Up power supply!"
