As mentioned previously the NF-A14 FLX is identical to the NF-A14 ULN except it features faster speeds. As a result the packaging is more or less identical.
The internals feature a list of key product features which can be found in more detail on product page here.
The main difference between the NF-A14 ULN and NF-A14 FLX in terms of accessories is shown below. The NF-A14 FLX features an extra adapter. It has both a Low Noise Adapter and an Ultra Low Noise Adapter while the NF-A14 ULN features only an Ultra Low Noise Adapter since its lower operating speeds are like having a Low Noise Adapter permanently built in.
The back of the box gives you a brief description and some specifications. The key specifications to note are operating speeds of 1200RPM (default), 1050RPM (low noise adapter) and 900RPM (ultra low noise adapter).
