Query: Very disappointing

The phone jacks on mine do not work at all. The phone cables worked just fine on my previous surge protector(which didn't have sufficient capacity hence my purchase of the Belkin). Even if the jacks did work, there is no room to plug in a two way splitter to support both the fax and phone that I need for my home office - you'd need to use yet another phone cable and a three way connector. This is very poor design. Further, the unit makes a slight buzzing noise when turned on. I won't be buying this brand again and will likely replace this unit before long.
