This desk extender is great once I figured out how to put it to the proper height for me. Four legs makes it too high but would be perfect for a 6' tall person. I found it extremely awkward to adjust the legs on both sides. Since I use it on my dining room table to knit while standing I'm kind of not looking forward to collapsing it completely and having to set it up and adjust it again. I hope it becomes easier with practice. Once set up though it is great for my needs.
