Monster has a long history of identifying scams. Then selling an equivalent product for much higher prices. For example, Monster marked speaker wire with end marked "Speaker" and "Amplifier". Monster said if the speaker end was connected to an amp, then music would be subverted. Many did that and said they could hear a difference. Scams are that easily promoted.
Then Monster sold that $7 speaker wire for $70. Many again knew it must be better because it was more expensive.
Monster sells protectors that are electrically equivalent to other plug-in protectors. None claim to protect from potentially destructive surges. Protection inside appliance is always superior to that protection. Do Monster also sold them - sometimes for $85 and $100.
Anyone can read specification numbers. Surge that can overwhelm better protection inside electronics must be tens or hundreds of thousands of joules. How many joules does that protector claim to absorb? Hundreds? Anybody suspect a scam yet?
Normally a thermal fuse disconnects protector parts as fast as possible to avert fire. And leaves that surge connected to attached appliances. A surge too tiny to damage electronics can also destroy that near zero protector. Grossly undersizing its joules means the naive will recommend it and buy more.
Sometimes that thermal fuse does not disconnect fast enough. These events have been too common: http://imgur.com/hwCWHMW
APC recently admitted some 15 million protectors must be removed immediately due to so many house fires. APC is a more honest company. Others (ie Monster) have same internal circuits. But will not admit to this problem.
If found in your luggage, that protector may be confiscated by a cruise ship. They take fire that seriously. Best is an adaptor without protector parts - that can even compromise (bypass) what is better protection inside appliances.
How many joules does that Monster claim to absorb? This is technology. If numbers are not provided, then one should always suspect a lie or scam. In this case, fire is another problem.
