I bought this cradle as a more cost effective desktop cradle than the Motorola one, and I'm very dissatisfied so far!
Firstly, it struck me as odd that the cradle plugs into the wall with an AC to Mini-USB connection (thankfully it comes with the right plugs). Unfortunately most engineers who have worked with cell phones or small-form-factor USB connectors know Mini-USB to be mechanically flawed compared to the Micro-USB like the phone itself takes. This seemed like a cost saving measure and technically still allows the dock to be used with a computer's USB port.
Secondly is a severely irritating flashing red LED. When the unit is plugged into wall AC power, the indicator light for the second battery charger shows green but very annoyingly flashes red 3 or 4 times a second. The only way to stop it is by putting an extra battery there. If there isn't a battery to charge it should just be off! Basic user interface theory says that a user interface should never get in the way or be a distraction, but compliment the use of the system its designed for.
Finally and most frustratingly, the touch screen on my phone doesn't work when the Droid X is resting normally (charging position) in the cradle! It seems that the phone's capacitive touch screen loses whatever voltage reference it needs to detect a finger on the screen when in the cradle. This is the same problem that keeps the touch screen from working in the car sometimes, or you rest it on just the wrong surface and try and interact with the screen.
*** Update: March 29, 2011 *** It's far worse than this after trying to deal with this problem the last couple months. Not only does the screen lock up, but it also suffers from phantom "touching" while in the OrionGadgets cradle. It's very strange, but sometimes I'll put the phone in the dock and I'll hear the haptic feedback periodically make a noise. Often the display won't change, but it's annoying when you're trying to sleep and randomly the haptic feedback sound kicks in the phone. On really bad nights, I'll wake up to the Winamp app playing music, or some other application open on the phone. This never happens in my Motorola car dock. Tried bringing the dock to work and it does the same strange behavior there.

This charger was designed by people who seemed to care about delivering a quality product, but the quality suffers because the engineers don't have experience designing for touch-screen based phones and didn't do any market testing before shipping. I'd steer clear of this one if you're considering it. I regret my decision to buy it.

Hmm, I find it interesting that the OrionGadgets user hasn't responded to this post. No matter, after dealing with the device for the last couple months, I'm sick of the problem and am chucking the dock and going with a Motorola dock. The Motorola dock in my car has been working great so I'm expecting the desktop dock to be likewise.
As an additional comment, DO NOT buy this OrionGadgets dock if you are using the extended battery for your droid X. The millimeter or so added thickness was obviously not taken into consideration into the cradle's industrial design (see my note above). It will fit if you jam the phone into the cradle, but I'm not going to risk damaging my phone's USB charging port, I've dealt with enough of that on my old Blackberry devices.
What the functionality? Or is it just like a free promotional gift to be used with something else?
