Got my today. Time to have some fun 
Assembled and initial test
First note: This model GUI/layout is a 1000% improvement over DPS series.
Assembly:+ Good and safe package
+ Housing is compact and well built, it's all to size and aligned
+ Stackable design
+ Manual is clear, all steps are there but could be better, for example put the screw image near the step, so we don't have to scroll up and down on PDF
+ Simple and fast assembly, everything is plug and screw type, no soldering needed
+ I check every crimp, they are crimped correctly and will not slide away, also they are isolated with the plastic sleeve
+ Rubber feet contain inside a metal washer in middle
+ RD fans are passive up to some temperature or amperage, so silent operation most of the time
+ Chassis is earthed by PSU screws, good continuity, almost no resistence
+ Used cables seens ok for the requirements
+ Lightweight (This is not necessary good)
- The DC cables that connect to the buck PWR IN are the only cable not crimped, they use soldered wires to screw to the terminal
- On PSU mount area i got some kind of double tape, not very sticky, not straight, applied bent tape over tape, looks like a mistake and they don't care to replace. Not needed anyway.
- My PSU fan is always on beside the note on top says "Fan have On/Off circuit" - not true, maybe they have speed over temperature adjustment but not ON/OFF, not loud but will disturb. Yours also too?
- AC switch on back - I hate this since i have large workbench with stacks of equipment’s and reach back mean get up, try to not hit stuff put my hand on back and find the switch. I know this simplify the build and cables routes but worth the effort and extra! Also, i don't like have power equipment’s always on, on stand-by, if i leave i want them dead, not sleeping waiting for a disaster to happen. Fortunately, i have a power extension on my side with some free sockets, each socket have independent switch so I can use that to fix the problem.
- MicroUSB instead of Type-C, not critical, we know is cheaper and easier. Better microusb then bad implemented Type-C.
- USB at front, we can hit the cable and it will stay at front of stuff, that kind of stuff should be hidden at back, we know module can be used alone, but a addon board could be made and with a flat ribbon cable connect from back to front to use with this enclosures.
GUI/Interface:+ A very big improvement over last model and beat many professional models out there
+ In general it's very easy to operate, every function is a pleasure to use.
+ Very easy to set desired voltage, click V-SET, type the volts eg: “5” button, click “ENTER” and is SET. You can also use the encoder to increase the values but that is slow and unpractical to me when you want go fast, many PSU still use the encoder only and arrow keys to set V and I which i dislike a lot, for example sigilent spd1305x.
+ Recals and saves are fast to set (3 button clicks), in comparison my sigilent spd1305x is a pain to do that and I avoid that function at all cost. With RD6006 is a heaven recalling.
+ Setting page allow you to customize important stuff, like Power on behavior, confirm before recall and save, power on behavior after recall, get rid of boot logo to instant boot times, select from wifi, usb, mute beeps, brightness.
+ Firmware upgradable over USB, no more board hacking
- Add a option to click and hold some key to switch between graph mode and normal mode -- Very usefull shortcut! eg. click and hold ENTER?
- Add a option to auto shutdown after x seconds on idle state, doesn’t hurt to have this as a optional option.
- Make use of press and hold to access recalls, lock/unlock, access settings, maybe add this option on settings and replace the need of shift by push and hold?
- When you recall a preset it show at bottom the number - That's ok, but when you change your output that should put an * near to indicate changes was made. Also when you save the preset it will stay showing the last recall, that's also wrong, should show last save slot instead because we are now using that slot. Eg: Recall M2, change output, Save to M3 -- This should put M3 at bottom and not stay at M2
- keypad follow PC keyboard numbering, personally i prefer phone pattern for this aplication (1 top left first, 2, 3)
- LCD show V and I below. But on GUI buttons that's other way, first button set I and second set V, that's a big no sense to me, if you look LCD and naturally press the key your brain will move you to the wrong button to follow the LCD pattern, even if you read button label fast you may go wrong button - This need training for me.
- Green terminal for battery charging, big mistake, I bet someone at any time will use this as Earth. Worse when is Positive rail! They should put that as a red like color, an orange for example. Also why not include a earth terminal too?
-> As a feature request would like to see RGB on I-SET and V-SET, and set them RED when OVP and OCP kicks in
App Software:+ Both PC and android app works fine to me, no virus detected by Kaspersky.
+ Software is responsive and easy to use
+ Can upgrade firmware via software, with check update function
+ Doesn't require ugly dependencies and services, work as portable
+ Almost every feature is avaliable there, beside some settings on menu page
+ Software show both normal view and power curve
- When using comunication this will lock physical access to the GUI, would be nice to operate both and sync
So far I only had time to play with user interface, no test made to performance or ripple yet. If things match up to specs this will be a winner product. No regrets so far.
EDIT: 20/11/2019Battery Charging:Tested some basic charging with Pb batteries 12V and ion cells 4.2v
At charge levels it behave like any other commun PSU but:
+ Fault detection, when shorting the output turn OFF and stay, to continue you need to turn on manually again
+ If voltage falls to abnormal value or disconnect a wire the output turns OFF and stay, to continue you need to turn on manually again
+ If you reverse the poles on battery connector while output is ON nothing happens, no power draw
+ When you set a voltage lower than battery source and turn on output it automatically turns off the output
+ When charge ends (at very low mA), output turns off
+ If you turn on output without a battery and then connect to battery output turns OFF, because of abnormal voltage detection, so you need to connect battery first and turn output after, nice one
+ If output is ON using battery connector, probes disconnected there's no flow (OL at voltmeter), it need to detect some source of positive voltage before start to flow current
+ While output is off using normal connection +V it show current battery voltage, this is not true if you use battery connector
- While output is off using normal connection +V, if you connect battery on reverse poles it shows 0V 3A draw and start falling down to 0 overtime (This happen with 18650 ion but not with Pb showing 0V 0.085A and fixed there)
- While output is off and connect a battery it won't show battery voltage like the V+ connector, but will show the voltage near battery icon overtime with a scroll
- When a battery is detected (Volts) battery icon turns red, why not green if ok and red if reverse connected?
- If you change voltage while charging, it will accept and continue, bad thing, so you can charge ion at 4.2V and then set 6V that will bypass. Please fix this! turn output off when change voltage in battery mode to be safe and let user turn output ON again
So this battery output is a win when using batteries, is there to be used so make use of it. The protections make sense and are always a plus.
