I have used this laptop cart everyday over the past 4 months for transporting my laptop room to room within the Rehab Facility where I work. The size of the cart tray is good for my laptop. I am 5’2” tall, and with the cart adjusted to the highest height, I am very comfortable typing on my laptop while I stand.  I am unable to lower the height of the cart using only my hands, so I do not try to lower it for sitting down to type on my laptop. The wheels make a loud rolling sound when I push the cart down the tiled hallways of the facility, with the sound increasing with the speed of my step.
