This product is amazing. I've waited a couple months to do a review so that way I could find all of its flaws. I've set it up once when I've first got it and my floors have been vacuumed twice a week, every week. I program it to vacuum at noon so when I leave for work in the morning, by the time i get home i have a clean home with vacuumed floors.
She is part of my family now. I've named her Rosie.
The only flaw I've found with this product is that the docking station that it connects to for recharging is very light. Sometimes Rosie will knock the station to the side which makes it impossible for her to re-dock to it; and i'll have to set her back on the station when i get home.

What's great about it: set it up once, and you're done
What's not so great: The docking station is too light.
I would recommend this to a friend!

With a digital voltmeter and display, 5 isolated and filtered banks and automatic reset, this power conditioner ensures that your home theater system and other electronic components remain protected from voltage fluctuation.

The only added feature to the M5400-PM that M5300-PM doesn’t have is voltage regulation. I would hardly call the regulator in this unit a voltage regulator. It is merely a transformer with four taps on it. When the sensor detects the voltage below 114 volts, it will switch over to one of the two higher voltages. Since it is a scalar voltage ratio, the output voltage will be between 115V – 124V. The same is true if your wall voltage goes 125V – 136V, it will switch to the tap which will lower by a ratio. This is the CHEAPEST voltage regulator in terms of design and cost. Given that, it is the most energy efficient which doesn’t mean a lot since it consumes 0.3 Amps with no load (that’s 36 Watts).
I looked at the FFT of the power going into the M5400-PM and coming out the unit and there is no visible difference. The measured THD (Total Harmonic Distortion) using a RSA3408B (Spectrum Analyzer) did go from 2.1% to 1.4%, but that is the same filter in the M5300-PM.
I also looked at the voltage on an oscilloscope and compared the signal before it enters the unit and on the output. Comparing the two reveals all the fluctuations on the line before and after remain the same. Meaning the unit will not condition your power to give your expensive equipment pretty clean sinusoidal voltages.
The so called voltage regulator in the M5400-PM in my opinion isn’t worth the inflated price tag. Get your monies worth and go with the M5300-PM if you need that many outlets.
And yes I have all the overpriced name brand home theater equipment that I desire to protect with what should be overly designed power management system.
What's great about it: Surge protection worth the value of the M5300-PM
What's not so great: Cheaply designed voltage regulator
No, I would not recommend this to a friend.
