VFM37 Camera shutter tester from Bucharest, Romania?

[Kino]

I am wondering if anyone has purchased one of the many models of shutter testers that are being offered on Ebay by the seller "VFMOTO"?

Anyone have any experience with these testers and can offer an opinion on their quality?

Here are the specs listed in the ad.

About the product:
- No battery and no maintenance needed!
- Standalone shutter tester with light source.
- 2.4 inch color display.
- Works for speeds up to 1/8000th of a second.
- USB-C power connector.
- Can be powered from multiple sources (power bank, power adapter, and other 5V power supplies).
- USB-C cable not included.
- Works for both focal plane and leaf shutters.
- Has a dedicated mode to make testing Hasselblad lenses easier.
- Shutter speed is displayed with 2 decimals. This is very useful at lower speeds.
- Sensor box is able to perform 24mm and 35mm curtain tests by selecting the appropriate option with a small switch.
- The 3 sensor cable allows users to perform stereo camera tests or custom focal plane curtain tests for medium or large format cameras.
- The tester can be used to test Leica cameras with a non removable back without removing the shutter from the camera. For this setting shutter tests are limited to 1/1000 and curtain tests are limited at 1/200.

I have 2 of his earlier models, and mine take 9v batteries. I have found them to be extremely useful and a great convenience, I keep one in my camera bag when I go on photo trips, just in case.
I have only used them for my leaf shuttered cameras, although I do have one with two sensors that will work with focal plane shutters and early Leicas.
I am entirely happy with them. I would guess the new ones are even better than mine.

Thank you for that information. Always good to check before buying; not that I always do!
