I bought these frames and have been pleasantly surprised by how sturdy and easy to put together they were. I made my own custom table top of 180x80cm and it very nicely fit on the frame. Comes with an AU plug so no issues there.
For anyone wondering, my display defaults to inches - to change it to cm do the following: 1. Hold 1, 2 and M down till the display starts flashing 2. Press 1 for cm and 2 for inches
