Product review (2 stars): Beautiful but...
We bought the Samsung RH299000SR side by side refrigerator on 6/26/14, during the 4th of July sales. It was delivered, at our request, on July 7th. The refrigerator design is elegant, sleek and modern. The handles are flush with the doors which gives it an interesting cleaner look.  The refrigerator door has the Showcase feature which is like a double door allowing access to items in the door by opening the Showcase door cover, without having to open  the door to the main compartment.

PROS: the space in the showcase door is very roomy and flexible. It has 3 shelves with dividers, 2 open drawers with dividers (you can roll them out when the Showcase is open) and a shallow bottom shelf.  All dividers can be moved out of the way to allow full use of the space.
The Ice maker is really efficient and the ice bucket has a great capacity.  The bucket is easy to remove from the door for maintenance or just to empty and save the ice into another container.
The electronic controls for the basic functions are easy to use.
The interior led illumination is bright and very effective.

CONS:
We don't know how the ice dispenser works because ours was defective. The flap to allow the ice to exit worked but the motor to turn the ice didnt.
The one sided handles are very awkward and counter intuitive. You have to use your left hand or twist your right wrist to open the refrigerator door on the right. It is not obvious which part of the refrigerator handle to pull to open the main door of the refrigerator or just the Showcase door.  It will take time, practice and frustration for it to become second nature.
The compartments of the showcase door do not keep temperatures consistent with the interior of the refrigerator. The temperature at the bottom shelf was more than 50 degrees and slightly progressively cooler on the others depending on their position.
The refrigerator door with the Showcase feature is very heavy to operate even when empty. If you don't guide it gently when closing it, it slams.
There are only 2 drawers in the refrigerator and one of them is not full size.
The freezer has four shelves and only 2 drawers, a third one would be more convenient.
The actual consumption of the water filter is not displayed, only when it is exhausted an indicator will turn on. My 12 years old Kenmore showed the percent left on the water filter life.

Conclusion:
Based on the awkwardness and temperature control problem of the Showcase door of the side by side, the ice dispenser malfunction and the other issues we decided to return it to the seller.  We replaced it with Samsungs 4 door RF30HBEDBSR model on July 30th.  It has 2 french doors with Showcase in one of them, a Cool zone drawer and a spacious freezer drawer. I have been monitoring the temperature in the different compartments of the refrigerator, the doors, the Cool zone drawer and the freezer and everything is fine. The Ice maker and dispenser work well. We will have a more comprehensive review of this model when we have more time to evaluate it, but, as of now, we believe it was the right decision.
