Best protection is already inside electronics. A surge that can overwhelm that existing protection is hundreds of thousands of joules. So read each specification sheet. Which ones absorb hundreds of thosuands of joules - and remain functional.
A completely different solution (also called a surge protector) means hundreds of thousands of joules dissipate harmlessly outside. A surge that does not enter the building does not damage anything. Once inside, that surge goes hunting for earth ground destructively via appliances. Some protectors (such as that APC) can even give a surge even more destructive paths through an adjacent appliance.
Did they forget to mention that APC (and equivalent $10 one from Walmart) does not claim to protect from that other and destructive surge. How many joules does it claim to absorb? How does its 2 cm protector part stop what even 3 miles of sky could not? They need you to ignore damning facts and numbers.
A 'whole house' solution is the only solution found in every facility that cannot have damage. This superior solution also costs about $1 per protected appliance - another damning number.
Did they forget to mention superior protection is already installed on telephone and cable - for free? That it is only as effective as the earth ground - that you provide? Why do so many recommend without even knowing of protection installed for free - and what is necessary to make it effective?
