We have what CS 650 and ES 700 APC also (tens of cuts and brownouts in 1 year !!! (Creches sur Saone-71)). So you guessed it, the two multi-tested qlques month. You just take the strip Belkin Europa for CS650; the ES700 is homeland outlet. One downside: the heads beeps 30 sec under power failure: it awakens those who have not closed their door by going to bed (children and adults).
