Review on ErGear Premium Single Monitor Stand Mount: 22-35" UltraWide Computer Screen Desk Mount with USB & Full Motion Gas Spring Arm - Adjustable Height/Tilt/Swivel/Rotation, Holds 6.6lbs to 26.5lbs by John Lewis

Initially I had the same problem with accessing the arm tension screw ("height" screw). However, I found that you can push down on the top arm attached to the table and get full access to the screw (see my picture). Not intuitive, and it's not explained in the instructions, but I wanted to make it clear. I rarely write reviews but wanted to make sure others weren't put off by negative reviews as this is a good solid mount for the price. **By the way, you can't pay me enough to write a negative or positive review to fool others as I basically buy everything in Revain based on other reviews. These words are mine :)
