I, personally, do not have these, just a set of good quality elastomer OE-style perches. These go a good job insulating vibrations caused by the wrapping and unwrapping of the spring during extension and compression. The "down" side is that as the upper control arm travels through its arc, the mount must move too, against its elastomer core and, eventually, will wear it out. Now, the same technology is used in leaf spring eyes, lower control arm mounts, idler arms and motor mounts so I don't have a problem with it. However, "rollerizing" certain parts to reduce friction and deflection can have its advantages. The idler arm and lower control arm mount top my list. The others..... meh......
Many people swear by them. I bought them for my pony and installed them a few weeks ago. Can't tell you how they work though since my car isn't driven in the winters of New England.
Saddles on the first Falcons were steel-on-steel construction. (actually
steel on steel with a oilite bronze sleeve in between)
The rubber construction bushings were an "improvement" in terms
of NVH. (Noise, Vibration, Harshness)
Light car, light suspension components and springs = overkill in terms
of needing rubber in that location.
Roller or suitable bushings for the saddles make the springs more
effective and the system reacts quicker.
Do you NEED them? If you're replacing those two pieces anyway,
why not and if you're building a track car you definitely should upgrade.

If you're going to get the roller perches, get the double roller ones. With the single roller perch, there is some binding with the shock. The double roller ones let the shock swivel independently and gets rid of this binding. We broke a couple of aluminum QA1 shocks due to this and have had no problem after going to the double rollers. It probably won't be as big a problem with regular steel shocks though.
I found that the roller perches helped a lot with how smoothly my car moved over bumpy roads (what I believe is called "compliance"), while traction in corners also improved. Normally those two (smooth ride & good traction) tend to be one or the other, so getting improvements in both was sweet.

I have had them for several years and they are a worthwhile upgrade. The only thing I would caution you on is they made my front end sit about 3/4" higher after installing them.
I haven't ever picked up a set of used perches that still move. Jus sayin...
if you are talking about the version with rubber, then i don't believe you should be able to move them by hand. i don't know about the bushed versions.
i wonder why Ford didn't make it movable if it makes such a noticeable improvement in ride quality and cornering? they could have made the perch similar to that used in the upper control arm bushing which is solid as well.

Can you explain?

Nope you shouldn't be able to move them by hand. The bushing is built specifically
in that manner. It is not one of Ford's "better ideas."
