No fault of the makers just was a little harder than I thought it would be. I am not in love with it but it is growing on me.

It's little lengthy for me, otherwise I'm OK

I found it hard to move on this thing. The resistance it a little too much but mu brother is sure using it.

Sooooo, this was truly a pain to install, but ended up looking great. A few tips:

-Make sure you have room under the shelf for the length of your screwdriver. I put mine over the bathroom sink and should have allowed an extra couple of inches of clearance because my screwdriver didn't fit. I ended up taking the 3" long bit off the electric drill and using a pair of pliers for torque to screw it in.
-Don't bother trying to use the flimsy anchors it comes with. They are soft plastic that bends and warps easily. Get better ones.
-Definitely use all 4 screws. The instructions aren't very clear on this. Those aren't extras - all 4 need to go in. There's no template so once you have your first set of holes drilled you need to use the brackets as a guide to mark where the second set goes.

So it was frustrating, but ended up being worth it for the $13 or so I paid for it.

Too hard  not comfortable I guess I can remove some of the filler to make it a little softer

Not bad , just a bit to much of an emphasis on dealing with the post charge history. Overall not bad.

It was a little hard to put up, it took both me and my boyfriend to mount the TV, but we got the job done. It felt like the TV was going to fall because it kept tipping but it's on there pretty good!

Now I'm no idiot when it comes to assembling things, but this thing went above and beyond being a little complicated trying to assemble. It was installing the resistance part that gave me fits. By the time I was done I was too tired to actually get on it and ride it. Otherwise since then it works well and accomplishes what I wanted it for.

It's really tough. I had a little problem with screen sencitivity. All in all, It did it's job well.

you need to look at a zoomed picture to figure out how to put it together, then it's not too bad.  had to put a couple of zip strips through  the top holes to keep it from coming apart.  it's substantial.

Lil difficult to install, And like others comments, pkg wires not # right. But no big deal. Much better improvement in response.

It's not bad... just seems too simple of a construct not to make it ourselves, lol.

Fairly easy install, except the directions had 2 inserted addendums, which caused a problem. As I had the whole thing installed and 2 of the fingers would not latch. Thats when I discovered the addendums, and the shims. Which corrected the gap. Some of the weather strip pieces (3) had come off in the shipping box, and would not re-stick. So off to Home Depot for weather striping.
