I rate this 5 stars - for what I needed it does a great job.  I was looking for something I could sit on my desk and charge my iPhone 3GS with a case on it.  It also does a good job at allowing you to push the iPhone buttons and not feel like you are going to break off the adapter.  I have a JBL On Stage Speaker/cradle and I have to take my phone out of the case and when I go to change songs and I touch the face, I have to be very careful.  But that is a different story (I love the sound of that and rate it highly but again that is a different story).  I don't know anything about the syncing problems that others have had.  What I like about it is the adapter is not fixed.  It can be plugged into the phone and then slightly leans back into the base.  It looks like the base would accomodate almost any type of case around your iPhone (you really need to protect your iPhone with a case).  I have a nice CaseMate leather case (again this is for a different review) and the Seidio works great with it on.  My wife has a clamshell plastic case and it handles it too.  So if you are looking for a nice cradle/dock, give this one a look.  I am totally pleased.  I don't write many reviews either.
