    easy to use but heavy

    I bought this item for my daughter because she want to play her Casio electrical piano outdoors. A portable power will be necessary since the instrument equipped with no battery. 900VA will be good enough for around 1 hour so the capacity is good. The product is strong but somehow a little heavy for a 15-year-old girl. Also 9 outlets are truly not necessary even you use as UPS--an extension cord can do the job.

    I am a huge APC fan! If you buy the latest technology, you need to protect it with a powerhouse like this one! APC stands behind their products too. When there was an issue within warranty period, they had a new one to me within days. Will always buy APCs for my surge protector needs.

    Had a blackout, I have this powering my network devices and a NAS storage device. Has it connected via USB to my Netgear ReadyNAS. I was out and got an email from the ReadyNas that the UPS was on battery power. A short time later I got another email that the power was restored and the UPS was back on line power. Pretty cool.
