Great - but can't use a case while docking

This cradle and charger are great.  Allows me to keep an extra battery charged for those times I'm running out and forgot to charge overnight. The one downside, mentioned by everyone, is that the phone fits snug without the case.  So, the case needs to be removed before docking. I have an easy case to remove, and I'm getting to like it without the case anyway...

The case is pretty much what I wanted, a slim stylish carbon fiber look with a bit of protection. The rubber lip is high enough to keep the screen lifted off of a flat surface and out any minor standing water.  I cut out the bottom  part of the rubber insert using the outer case as a guide so that I could use the standard docking station without having to remove the case.  Still not sure why they can't figure out a docking station that works with a case?

The docking station fits the GALAXY Samsung SIII, and was delivered as agreed.  The only problem I have it does not fit with the Otter cover on the phone.  Otherwise this is a great dock.  It does not go into dock mode unless you do it manually.

I like the case a lot, but I was unaware that it would be practically impossible to take off! Otherwise, it's great.

Even with a slim case my iPhone 6 won't dock to charge. This was disappointing and I've already dropped the phone with the case off first thing this morn as I had to remove it to dock the phone overnight ... The sticker on the product says that if the case is interfering with charging then remove the case or call customer care. I emailed customer care and they responded saying to do a google search for dock friendly cases...( I had already spent quite a bit of time searching before emailing so this was not helpful). I was hoping for a bit more help in terms of what specific cases worked with this product for iPhone 6. :( I like the product but with 3 small children  I need a protective case on all the time.) I should have read the reviews more carefully...

Update - I took the device into a local cell phone shop and with their help I have found this case which works - as you see the bottom is open almost to the edges. No problems using the device now and I'm very pleased with its performance

Works great... but will not fit if you have a case (and who wouldn't) , unless you remove it.  Poor design choice there.

Great docking solution. I bought this for my wife to use on her nightstand so that her phone would charge during the night. This works perfectly. No problems using this with or without a case. The best part of this dock is the rubber on the bottom. It keeps the dock stable and stops it from sliding while docking the phone. This is a great dock for the price!

After reading some of the reviews here, I decided that this little dock would be great for my SG2, especially because it would let me dock my phone without removing the case.

Well, I was WRONG. This might work with some cases but NOT WITH ALL OF THEM. If your case is thicker than 1.5mm (to be specific, eg: D3O sold by Tmobile) this WON'T work.

So, please, don't be deceived by the "You can dock your phone without removing the case" statement from other reviews.

PROS:
- Cheaper than the Samsung Dock
- Nice looking
- Easy to assemble
- Lightning fast shipping

CONS:
- Half the price but also half the quality compared to the one by Samsung.
- Phone with cases which are 1.5mm or thicke cannot be used with this dock
- SGS2 with large screens seem to be a bit unstable.

I love this case. It's well made and stylish. The only drawback I have with it is that I need to remove it from the case to use the dock connector. I've installed an iPod car kit and have some peripherals that require the dock connector, such as the radio remote. I hate having to take the iPod out of the case in an environment that it might get damaged in, such as when connected to my car stereo. Otherwise, this is a great buy at a fairly low cost.

The case is very nice looking; looks high quality and expensive to others. It also protects the phone very well, feeling sturdy.
The problem, however, is that it is not a convenient case. It is impossible for me to dock my iPhone on to my external speaker system due to the 'rubber flap' covering the bottom; it just falls off the dock. I know I have to remove the phone from the casing if I want to enjoy my music.
The top headphone jack 'flap' is very difficult to flip up for headphones; making it virtually impossible to use your headphones while in the case.
Finally, it feels a bit cheap after removing and putting on countless times because of the stupid flaps. I am afraid the rubber will tear very soon.
Overall, a great case for the web-surfer but not recommended for the person who wants to enjoy music on their iPhone.

Case won't fit with dock station, also it does not fit fine

Almost every case that I've had has either made it difficult - or impossible - to use with a docking station.  This solves that issue by plugging in to the docking station, and extending the connector to your phone.  I use it almost every day - it allows me to play music through my docking station while charging the phone.  Without having to remove the case on my phone.  Does exactly what it is supposed to do.

I love not having to search for the correct cord to plug my phone in.  This docking system is great!

The dock works great with my S3 in a Diztronic case.  Just take out the little insert at the base of the dock and the S3 (with case) fits like a glove.  The only weak engineering on the dock is the power connector to the phone.  It is thin and narrow (that is just the way Samsung designed the port on the S3).  Anyway, I can see me one night putting the phone on the dock and breaking off that connector.  So far, so good, hope it lasts.

For the most part, I like this product.  It works well for connecting to your television and stereo while keeping your Zen in an upright position.  The only problem I've found, like many others, is the fact that it's nearly impossible to use this product if you want to keep your Zen protected with a case.  For me, it's worth taking it out of the case because I don't carry it around with me all the time.

This dock works really well. Sturdy connection when in use. I have the Phillips 2 piece-dockable hard case which works really well in this station. Glad I bought it would buy another if I needed it. The only thing that would make it better is if it had a speaker on it that made it louder for notifying when a call came in. Other than that its perfect.

Item is good for what it is - but even with a slim case (Finite) on my tablet, it will not dock.

Samsung probably designed this to work only if you use their case.

Sure, I can take the case off and dock it - but why bother with a dock then.
