I am a disabled artist with back pain, and many other disabled artists encouraged me to get the sketchboard, telling me it was great for posture and helping prevent back pain. Well, I've been using it for a little while and I haven't had much back pain yet, so...perhaps that claim was correct!From what I understand, this is meant more for desk use than lap use, and I think that's true. It feels very awkward and large when I try to use it on my lap (unless I am in the perfect position), but at my desk, it works beautifully as an easel. The edges allow me to rest my arms, and I can easily slide my arms about as I work, no awkward edges. The legs included are pretty cool too, I can prop it up at the perfect angle, which I have found is the middle setup for me.I only have two complaints:1) Only a couple days after receiving the sketchboard, the magnet in one of the legs fell out. Slightly annoying, but I figure some superglue can fix that. But the people making the product may want to check those to make sure they're glued in properly before shipping.2) I kinda wish there was a higher angle to work at. The low angle is, well, too low for me, and the high angle is not right either (seems more aimed at using the ipad as a screen than a drawing tool). The middle angle is okay but not perfect. I feel like it would help my back pain more if the angle was just a tough higher. Maybe in version 3? We can hope.All in all: Don't like the price, but boy, I'm glad I got it. I feel it's a much more ergonomic setup for drawing.
