I wish it were a little higher, for reading and typing comfort, but it's not bad, for free, compared to the cost of the ones I've head were designed by the May clinic.
The desk top is a length of left-over closet shelving. I set it at a slight angle, then ran two bungee cords from a wire in the middle of the shelf, up and over, to grab the backside of the treadmill's console. Then, to make sure the cord tension wouldn't make the whole think flip over, I also fastened the desk to each arm of the treadmill with small bungees.

Also, using the wire shelving rather than a solid piece of wood allows me access to the buttons when I want to increase the speed, change the display, or whatever.
I've walked off 2 inches from my waist in the past 5 weeks, (yay!!!) so this will provide an additional way for me to walk when I'm trying to plead heat and humidity as an excuse not to walk.
It's also easy to disassemble the whole thing if my husband wants to use the treadmill.
Oh, and one other item I employed: A roll of that non-slip rubber you can buy at the dollar store. It works great to keep the laptop from slipping; it really feels quite secure. I rolled up the lower end, to raise the bottom of the laptop a bit, for better keyboard and screen position.
