I should have looked at the picture more carefully. This test board has IPEX cable connectors. Besides being very small and somewhat tricky to use, these connectors are rated for only a small number of matings (about 30). Disconnection should also be done with a removal tool. This is not really usable.

What it did was OK. Unfortunately the touch screen would not calibrate and it was impossible to use the stylus to choose the top line of the menus. The other menu items were hit and miss. Sometimes the area the touch screen activated was 1/2 to 3/4 inch from where I touched it. The number pad was similarly impossible to use.The other major problem with it is the USB drivers would not work on the latest version of Windows 10. The windows installer suggested using settings for Windows NT, which didn't work either, which would have clearly made it impossible to upgrade the firmware as the device was never recognized by windows.Best advice - avoid this product. There is clearly no QA and doesn't seem to be any reasonable software support either.

I can't get the touch screen to calibrate. As others have reported, after attempts to calibrate I can't activate menu items in the top right corner (note 'calibration' is only at two points, upper left and bottom right.).I'm reluctant to return, because otherwise I love it, you <can> do everything using the side buttons (in fact might be easier), and the calibration is close enough to be ok for the numpad. Build quality seems good, solid metal case, complete set of accessories, 300 pts, learned more about my efhw in 5 min than I had known after tweaking for weeks. Hmm** Update ** touchscreen acceptably calibrated. I <think> it's static sensitive. I held port 1/2 while calibrating with the pen, and got the vertical calibration within usable range. So I guess it's a keeper. Don't forget to save the touch calibration!

Be aware the connectors on the test cables that connect to the PCB are only good for a hand-full of connection/disconnection cycles before they break

Very helpful.

Excellent quality and detail. 5 Star Rating!

This one works fine!

Excelente relación calidad/precio

Excellent product however, the cheap plastic box hinges are broken. Thus the 4 stars. Trying to source a new one but seems impossible.
