The first question is, why another UNO board ? The answer would be answered in my short review below.
This CT-UNO was used as part of the starter kit during my Penang Mini Maker Faire Arduino workshop in November.
The main factor I really like about this is the Micro-USB port instead of the gigantic USB B plug used by regular Arduino UNO boards. With so many USB micro cables all around, having a USB micro is a good decision made by Cytron.
Secondly, I always like the FTDI USB Serial chip. I'm still using the FTDI Breakout board on a regular basis to program the Arduino Mini Pro ...
On the subject of FTDI board, there is an Android app called FTDI UART Terminal that can accept a FTDI USB-Serial device so that you can plug in the CT-UNO directly to the Android Smatphone and view the Serial Monitor using this app with an USB OTG cable.

As per most of the newer UNO board, this is a SMD version of the atmega328P, so you cannot remove the IC.
Another thing I really like about this board is that you can directly solder wires to the pins below the board for permanent connections. Here are some pictures of the CT-UNO on the sides and below the board.
Overall, it is a very usable UNO board and very good to view Serial Monitor on Android Smartphone that support USB OTG cable.
