Disclaimers
Ceramic based clutch discs intend to increase the holding capacity and durability of the clutch as opposed to an increased life expectancy. Using a ceramic based material for easy street driving may contribute to premature wear of the clutch kit due to the harsher engagement and because of the higher tendency to slip the clutch during street driving.

*Increase in holding capacity is rated in Crank Torque, not Wheel Torque

well designed
I have two of these. The number and orientation of outlets has fit all my needs. I haven't needed the USB's yet, but I'm glad they are there. The thin plug and off-center angle are very useful. One is in use under my three seat power reclining sofa, guitar multi-effects, and a couple lamps are plugged into it. The other is in a drawer powering the air pump, power filter, lighted hood and heater for the aquarium on top of the dresser it is in.

Ideal - Organized and Many Plug-in Options
Size: 6ft Cord, Color: 20W_Black
Just what I was looking for at the bottom side of my bed stand to keep 5-7 cords organized and the area clean, .... clock, lamp, chargers, infarred heating pads, and other plug-ins and charger cords as needed.

Needs better hardware
Size: 6ft Cord, Color: 20W_Black
Yoooooo great product but what is with the comically tiny screws? Actually installing this on the underside of a wooden desk is near impossible unless, of course, you are in fact a Disney princess and in charge of a team of handy-dandy mice all with #0 Phillips head screwdrivers and 5/32" drill bits. They drill, you hold, kind of thing.

Great for cable management
Size: 6ft Cord, Color: 20W_Black
If you are obsessed with keeping cables neatly organized for your desk, this is the perfect power strip to get. It comes with decent enough screws for mounting that will hold the weight of all the cords you plug in. The outlets on all three sides is very convenient and makes it a snap to fit all your devices in even with some having very large adapters on the plugs, which often take up a majority of the power strip. I have already purchased a couple more so I can organize my wife's desk and one of my kid's desks.
