Question: Would this work mounted on a treadmill to hold an ereader?
Document: When I first installed this arm it worked great! I loved it. Everything held in position, but no longer. I find that the internal gears, likely plastic, have worn down and will not hold in position. The cranks work fine but the main adjustment is trashed. I would say that if you were to mount this once and not adjust often then it would likely work. It is not built to withstand a lot of changes.
I bought not knowing how well it was going to work, since I wanted to mount it onto a treadmill so I can watch while running and it turns out it works great. Firm grip of the iPad with little movement. No problem tightening it to the position that I wanted. You can slightly move the orange stoppers opposite the screws to really crank it tight,
I needed an IPad mount for my sauna. This was easy to install and takes some work to get it at the right angles, but it does hold my ipad securely. It does not adjust to hold my ipad mini, only my standard size ipad.
Great little piece of equipment. buying more. Much more sturdy than I would have expected.Mounted on the wall for getting off counter. Great.
I bought this because I wanted to mount my original iPad under my cabinets. I really liked that the base swiveled and it had so many points of movement. The installation was easy enough but once I mounted the iPad the joint at the base couldn't hold the weight. As I tightened the thumb screw the metal screw simply stripped the plastic threads rendering it completely useless.
So...boo on my part, but the contruction of the mount looks great and would look nice mounted to a wood desk as mounted to a wall. It says that this is to mount a 10 inch tv, but I was using it for my iPad and it held the iPad nicely too.
This product may do well for wall mounting but the joints seem a little weak for under-counter mounting. I placed the Mount-it in the kitchen to hold an Ipad 2, mounted under the upper cabinets. Even the light weight of the Ipad requires repeated retightening of the joints to hold it constant and steady. It's ok for now (mounted one week), but I am afraid, over time, the joints may not hold. The sections of the arms are metal but the joints are plastic.
I don't know why.. I thought that all 3 legs were adjustable and this thing would accommodate a large variety of sizes.. but no. The top one is adjustable. I was mounting this on the wall above my treadmill. So far, if the joints stay nice and stiff, I think we'll be good. I can angle it backwards so that the kindle is leaning back and it shouldn't jiggle out (since I can't adjust all 3 legs to get it in tightly). So, we'll see.
Not so much a TV mount as a tablet holder. Too big for my Nexus 7, but seems like it would work fine on an 10 inch tablet tho. I actually modified one to use as a small keyboard holder and it does that pretty well. Plastic-y feelng, but hey, works for the price.
I have 2 10"car tvs i would like to mount in my conversion van.. i was wondering if this would mount in a vehicle and if it would hold the tvs?
Answer: Sorry but no, because it mounts with screws. If you had a wooden surface or similar material on your treadmill that you could attach it to, than by all means go ahead, but unless you have a place to mount it with screws, you cannot
