These radios are available in either kit form OR fully assembled...but that's not what makes them unique. I have written before about the Chinese versions of Dave Benson's (now Rex Harper's) "Rockmite", known in the PRC as the "Octopus". The Octopus is LOOSELY based upon the Rockmite...and the Super RM clone is even more of a departure.
I bought one of these radios for portable operation with an Opek HVT-600 antenna while at the YL's house.
The BEST part of this radio is the WHOPPING amount of power that it emits. The CRK-10 was a stout little performer with its 3 Watts....but the Super RM Clone is an EIGHT WATT RADIO (@12V DC).
There are some interesting upgrades with this particular radio, as well. There is a DB9 port on it for what the website calls "PC Keying", but the software is difficult to find, as is the cable required to make it happen. After quite a bit of navigating around ENDLESS Chinese websites, I was able to find the software, schematics, and instruction manuals for the rig.
The Super RM is far from perfect, mind you. The audio is anything but pleasant to listen to IF you are using regular (a.k.a. CHEAP earbuds....or "walkman" style headphones). It is SO LOUD and SO HARSH as to not be comfortable for very long. And, without a little tweaking of the sidetone pitch (via button 1 and 2 on the top of the circuit board), your keying sounds will drive you CRAZY.
The solution was fairly simple for me, since it had worked with the MINT CONDITION Heathkit HW-7 that my ex-wife bought for me last year: 1945 vintage Telephonics Corporation TH37 headphones and an OLD MFJ-CWF2 filter.
The old heapdhones in conjunction with the filter (when needed) really take the harshness out of the audio. Your mileage may vary, but it is an ABSOLUTE improvement for me.
There ARE a few significant downsides to this radio in the "assembled" state: ALL of these radios are coming from China with crystals for 7.023 MHz. Extra Class license holders are the only ones allowed to use this frequency. ALSO...the Super RM Clone uses THREE of the these crystals. Two are for the filter, and the third is for the oscillator. But, affordable crystals can be had by contacting Rex Harper via QRPme.com.
I QSY'd mine to 7.030...the QRP "watering hole" for 40m CW.
And there is no case with the radio. However, the matching aluminum box can be obtained by a quick trip to eBay.
All in all, I paid $40 for the assembled kit, and another $15 for the matching aluminum box. And when you purchase from the MANY eBay sellers, shipping from China is USUALLY free...another perk. Arrival to the US is typically 7-15 days....mine came in 11.
More of these rigs can be seen on China's domestic shopping website, Taobao.

As I make changes and improvements to the radio, I will be posting them here.
