Mine is the same as yours Dave

I had doubts about mine when I bought it. As an inexpensive unit it's not coolant or swarf proof. I also wondered about accuracy, repeatability and battery life.
In practice it works very well and it's still going strong after nearly 3 years. It's on it's second set of batteries.
I've had two small problems with it. Firstly the X scale shifted slightly after a year causing the sensor head to bind and jump after moving about 50 – 100mm. My fault – a fixing bolt wasn't tight. Second problem: at first I mounted the display units on the control box. One of the USB connectors is loose and the shock of the contactor operating was sometimes enough to wobble the connection and lose position. Moving the display away from vibration fixed that.
So far moderate amounts of swarf and coolant on the scales hasn't done any damage. Fingers crossed!
