I bought 2 to fit my employer's Veridesk machine and I couldn't be happier. The quality and durability of the gun really surprised me for the price. Installation was easy and quick; Tools were provided and helpful except for a Phillips head screwdriver which I needed to mount the plate on the back of my monitor. The level of flexibility and freedom allows me to set the best possible images and I would highly recommend these units to anyone looking for a quality yet economical monitor arm.
