Take a $3 power strip. Add some ten cent protector parts. Sell it for $7 in a supermarket. Similar circuit sells in Walmart or Staples for $25 or $60. Or Monster sells a similar circuit in Best Buy for $80 or $150. When does a profit margin become excessive?
Read each numeric spec. No power strip protector claims to protect from typically destructive surges. None. But don't take my word for it. View numbers for protection from each type of surge.
Destructive surges are typically hundreds of thousands of joules. How many hundreds of joules does that power strip claim to absorb? How does it make hundreds of thousands of joules just magically disappear? It doesn't. It makes money disappear.
Monster has a long history of identifying scams. Then selling similar products at even higher prices. Because it costs more, then many will recommend it.
Either a protector connects a surge short (ie 'less than 10 feet') to protection. Or it is ineffective. Any facility that can never have damage always upgrades earthing. Uses a 'whole house' protector. And wastes no money on power strip protectors. What does Sun Microsystems recommend in their "Planning Guide for the Sun Server Room"? Whole house protector. Not power strips.

Power strip protectors too close to a computerized appliance and too far from earth ground can even make damage easier. Can compromise protection already inside the appliance. May also create house fires as demonstrated recently by Whitneyd88 entitled "My house caught on fire and my tank busted" at:

Protection is always about where energy dissipates.
Read "saved by surge protector" for protectors that do what is even routine in munitions dumps. Because munitions dumps also must have best protection. They do not waste money on power strip protectors. More important, they upgrade the only item that provides protection - single point earth ground.
What is necessary to protect power strip protectors? One properly earthed 'whole house' protector.
