This "J69" looks interesting - I like that it at least has replaceable standard batteries.

I'm somewhat sceptic, though, because there seems to be no in-depth information from a named manufacturer - what about a manual, test samples etc.?

Found a user comment and some video on the J69:

Nice find! Here is another link for the same gimbal in US$ http://www.goodluckbuy.com/beholder-handheld-3-axis-gimbal-stabilizer-ildc-brushless-gimbal-for-gh4-gh4-nex-sony-a7-bmpcc-.html

It got qr plate design which is a nice bonus, but looks like all 3 axis is fixed and non-tunable, that could really limit what setup it can use.

I just read an article from cinema5d introduced a brand new handheld gimbal for a7s and panasonic gh4-MOZA Lite:

Hey Guys,

I am seriously considering pulling the trigger on the Beholder gimbal mentioned in previous posts. Almost bought the Nebula 4000 Lite, but then found Dave Dugdale's review and he mentioned the Beholder that was at NAB this year. He will be doing a review at some point of the Beholder, but I don't know when that will be. Attempts to get a response from Team Rebel Design who make the product have not been successful, which is obviously worrisome...

Pilotfly H1 with GH4 12-35mm (Portrait supertones setting)

Out of the box, quick balance, quite a windy and high-contrast day - some overexposed shots for sure. The 'dolly' shot with house in background has slight post stabilisation because of microjitters. PIDs from pilotfly seem to have sorted those out since then. Some of the shots are at 35mm and still look good. The shot in the barn is what I'm most excited about because you have that added level of polish and control - it lifts it from a home video to 'cinematic'. The tilt up/down button is going to be a useful tool, very smooth and with a bit of practice should be precise too. Can't wait to use it for a wedding. Critiques and feedback very welcome.

Beholder MS1 vs. Nebula 4000

Cons: Only two profiles for work, joystick works at both. Less space behind the camera, but ok for most autofocus lenses.

Pros. Works out from the box, no need calibrate, just 5-seconds gyro calibrating. I like its factory calibration more than my Nebula, where I made it with privet technician 5 times. About 4 hours netto working time. Brutto it's almost 10 hours. Cheap replaceable batteries, you always can use second set. Beholder branded standalone charger for batteries and same batteries you can buy from aliexpress. 17$/24$. Very strong motors!!! It holds weight much more than Nebula. You can now make some manipulations with a lens or camera's body and Beholder MS1 not go crazy. Real life experience with heavy lenses like Nokton 25 0.95, Olympus 75 1.8 (Nebula can hold it only with huge vibration, not for real shooting) Joystick. I found it very helps for some situations.

Its 8 bit system makes me feeling of 32 bit I tried with another gimbals. It's faster to take Beholder from the bag and start shooting. You even can put you balanced camera on Beholder to its bag or your backpack without disassembling. At that case beginning of shot will start after few moments (now I think it very useful at vocations too). It's very compact at bag. Calibration gyro (5 seconds on table) is only maintenance you need do if you put lenses with very different weight. Big USB on the handle used for small USB light (included) and as charger for mobile phone (you can use it instead the cameras LCD)

Wieldy gimbal
