i already have one of these, so when i needed to put another tv on the wall in another room why wouldnt i get the same one? a third of the price you could pay, but at least half the best buy price.
the product: supports most vesa standard mounting types, i just put a 40" led tv (25lbs) on this mount and it stays up just fine, this mount holds up to 60lbs, my 60" plasma weighs 66lbs so that will give you an idea of how much a tv weighs.
this mount has tilt up and down and side to side with a full motion, i use it when i am in bed and also when i am on my eliptical machine on the other side of the room, i just extend it out away from the wall (about 10 inches) and swing it around so i can see it while i am working out.
it is constructed really well and looks and feels solid, high quality product 5/5.
a really great design in this product is the mounting hole placement, there are only two and they are vertical so you only have to find one stud in the wall to mount it.
uses two screws to mount on a stud, not sure if they are included or not but you can get them at any hardware store, make sure you get screws that are rated for 100lbs or more to be safe, and you can find the stud on your wall by doing one of the following: try a magnet and run it along the wall until it sticks, if it does you have metal studs, you can drill right through them, if your studs are wooden, you can just knuckle tap the wall until the tone changes from hollow to dull, if you live in a newer house the studs should be 16"(center to center) apart in the wall, measure 16" from the left and right of the nearest light switch on the wall (the light switch casing is attached to a stud in the wall, it is either on the right or left of the stud, so you know for sure that the first stud is there),mark a little x on the wall on both marks and tap to see if it sounds hollow, the duller sound should be the stud. if your house is older the studs may be 24" apart. you can buy anchor bolts that will hold a tv on the wall by just going through the drywall, but i wouldnt do that, too risky!. dont be afraid to do it yourself, its easy, you could also run your cable from your box inside the wall up behind the tv, no one will see behind there so it doesnt have to be pretty, just run a level up the wall from the cable outlet and make a small hole and fish for the cable, you can do it!, a plate for the wall costs about $2. good luck! :)
