I SO wanted to give this a 4 and even a 5 star rating. THE PROS: - Perfect size for my Ikea MICKE desk (side storage model) - At 5'6", when fully extended, my laptop sits at the perfect height for me, even good for typing with the use of a stand that angles the keyboard - Light weight enough to be easily manageable (not cumbersome) THE CONS: - It comes with 3 PRESET height adjustments. Had it a 4th (between rest and and 1st height) the presets wouldn't be a take away. But Sometimes I need to lift my laptop about 6/6.5" while seated; this helps with posture, especially if you have back injury. (-1 star, as this is major) - I feel like most other models would have this is a con: not because I'm standing do I want my mouse to follow me to that position too... It's more natural to use the mouse at a lower position. So either a dropped attachment (something that can easily clamp on and off/store away) or someone PLEASE invent a height adjustable mouse pad to pair with the converters. I sub in a small 4.5" x 4.5" x 7.5" tall box when I'm standing for now. (-0.5/1 star)
