Lightweight projectors will mount easily enough to this mount. The arms aren't particularly long, so it may not work with larger projectors at all. They are also flimsy, but that shouldn't be a big issue.
The extension arm is nice. As long as you want your projector dropped exactly 5.9" or between 18.1" to 28.3"... Better NEVER get a projector that needs something different, because this mount is not so universal as to allow for that.
Now look at that pole - it's not exactly a locked in piece of steel. It's square tubing, and that means that it can have a bit of rocking to it. Maybe it does, maybe not, but you want to be sure it's not easily jostled.
There is no obvious quick release. It looks like you must completely remove the roll adjustment bolt to take the projector down. In which case you must completely readjust the projector when it is reinstalled.
Likewise, the mounting point isn't a secure point, but just hung, which means it's (again) a flimsy point.
Now the headache comes when you start trying to tighten things down. You do get separate roll/tilt/yaw points, with the yaw point being up at the ceiling (yeah, that's not going to be wobbly at all). That's good that they are separate, but the use of single bolts to hold things down means that when you tighten the bolts, the mount is likely to shift slightly, which makes the setup difficult. You align things perfectly, then tighten the bolt, and let go - and it shifts half an inch, or more. You loosen it, then try again. Half a dozen (or more) tries later, and it all lines up. Then you adjust the next thing, and go through the same process. Hopefully, not messing up the thing you just got perfect.
This is 'typical' of cheap mounts. It doesn't make them unusable (all reviews to the contrary), but make sure to read the negative reviews. There are a number of Epson owners who complain that it doesn't fit their model. There are several people who are complaining about drift and sag as well. The complexity of getting it all together out of the box is apparently a pain as well.
Reading through many of the '5-star' reviews you get an idea that many people have no real projector mount experience. Others who are giving it 5 stars are still complaining about the things they have to do to get it to work right. (5-stars? Really?)
This is a average 3-star projector if you consider 3-stars 'average'. It's not a 5-star model by a long shot. If the price was higher, it would potentially drop to a 2-star product. It's just very typical for a cheap design, and many similar models are out there. I think there are a fair number which have better 'universal' support.
As you browse through Amazon, you see dozens of mounts which are very similar to this. Some have better universal connections, but are flimsier. Others are stronger, but have less flexibility overall. Some look nice, and the nicer they are, the higher the price is.
So, what's a decent bang for the buck mount?
That mount, while not perfect, and far from the Chief/Peerless quality, offers a lot for the money.
First, it still has the separate 3-point individual adjustments for roll/tilt/yaw. It also has a separate release which doesn't require you to change those adjustments, but it's not built well enough to not shift a bit when you do remove things. It uses standard 1.5" pipe, so it is infinitely height adjustable. It comes with a 1.5" pipe so you can hit a couple of heights, and extensions are available from them, or any manufacturer who makes adjustable 1.5" pipe fittings, or you can get the length you need at Home Depot. It comes with (what I consider) the absolute best flat ceiling bracket I've seen. Not crazy overbuilt, but a very nice cover with a simple design that you can't buy 'separately' which sucks.
Universal design is not nearly as universal as it should be and is similar to what you linked to before. It is also more ideal for lighter weight projectors.
As long winded as that was, I hope it helps you understand what separates the cheaper models from the more expensive ones. I truly believe that if a good engineer were to sit down and design a 'cheap' mount it could be done for a ton less money than what Chief and Peerless charge for their more standard mounts.
