Ok to be honest I'll come right out and say the instructions suck! Having said that I'm writing this review to inform other potential buyers and hopefully this will help you decipher the hieroglyphic instructions. Before we start I will say this is my 3rd TV I've mounted, I'm not a pro but I suggest if you go at this you should be at the least mechanically inclined. If not, higher a pro. This is the first time I used a low profile picture frame style mount with an LED TV. I will say this isn't like the other pic frame designs as in there is no cable and you can remove this mount after installation more on that later.What's inside the box:The mount and associated screws, washers, etc..Mini level (I recommend using it as well as a real level when installing this to confirm the set is even).TWO(2) sets of instructions each labeled a roman numeral I and II respectively.Warranty infoMaterials installation suggestion sheetWall mount templateI installed my 2012 Samsung 46"" ES6003 LED TV into 3/4"" drywall but I was lucky enough to be able to use my stud finder and drill both brackets right into studs. I don't want to even go into using drywall anchors or toggle bolts. Anyway for my tv I had to use the deeper 40mm mount, Instruction sheet I will list which category your set will fall into and this is where you must decide if you can even use the lower profile mount. If you can and want to use the shallow 17mm mount stay on sheet I, for the deeper 40mm mount you refer to sheet II.Now take the template and decide which distance you must use to mount the brackets to the wall (there are 3 distances to choose, I had to use the middle option for my set). Then you measure and determine how you want your set to be placed, use the mini mount stickers to hold the template in place on the wall. Stick the mini level on the adhesive in the center of the template, I also made sure the template was stretched perfectly and used a real level to confirm the template being level. Drill 4 holes into the template (I think I used a 5/32 drill bit, it's pretty tiny), depending on which mount size you use you will drill holes marked either ""A"" or ""B"", I had to drill in location B. After that I used a 19/64 drill bit to widen the holes, you might be able to use a 5/16 if you don't have that odd size but it is a tad bigger than the instructions call for. Next you hammer in the 4 plugs from bag B, mount the bracket (either the 17mm directly or the larger 40mm). If installing the 40mm you will screw the zinc coated metal bracket on, place the black thick bracket cover over the zinc bracket and then screw the 17mm bracket on top of it all.The hard parts done, now just put the proper mount on the back of your TV set whichever instruction sheet I or II calls for (again dependent on what tv set you have). Now get a friend to help you lift the tv and click the tabs into the mount, once they click you pull the tv down slightly to lock it in. This is reversible by tilting the set and using a Flathead screwdriver to push the tab on each mount back and push the tv up (easier said than done but possible.. recommend using 2 people to do it). Now take a real level and confirm everything is even, congrats on your beautiful new mount. I took my time and it prob took under 2 hours to do. Goodluck!
