mine arrived (with free gift). did a quick test and some pictures...
pros:
1) good build quality and GUI/buttons (with LED)
2) large LCD for such mini device (and colorfull GUI too)
cons:
1) there is full swing signal burst for about 10-25ms on relay click amplitude transition, 2 to 2.1Vpp, 0.4 to 0.5Vpp, 0.1 to 0.2Vpp, 20 to 30mVpp (50 ohm load). the worst is transition from 2 to 2.1Vpp (10Vpp or 23+dBm burst) see attached picture (DS1Z_QuickPrint1.png - DS1Z_QuickPrint4.png). it maybe can damage sensitive RF circuitry (or not? i dont know, maybe it depends) but it should not be happening.
2)no frequency sweep sigh! correction: yes they have sweep function, its called "Line". so yes, they have no sweep function, but "Line" function (shaking my knee fall and slip carefully

)
as i dont really need modulation so far, so i dont test all extensively, only did some quick test on AM modulation. but it does have many modulation options such as sine/square/arb etc on AM modulation, not sure how important this is. from experience, i usually will use sine wave only mostly,
but lack of sweep function to do frequency respond of a DUT make this device a bummer (use Line Mode for sweep, my bad terminology

). if you dont care
2 1 serious cons mentioned above, this is a cute little device with easy to operate and change parameter using numeric pad.
what ataradov mentioned also confirmed, there is a bit of space between GUI/LCD pcb and FPGA/AWG pcb, so we can add holder for, and battery/fan circuitry pcb there for improvement if needed. the output is using THS3092 if i'm not mistaken from the picture and give nearly (flat?) 10Vpp (50ohm load) up to 10MHz this maybe good or not depending on how you used to (attached DS1Z_QuickPrint5.png - QuickPrint8.png)...
