should the moving part on the back sigh wabble?

Not sure what part you're talking about for sure but...I installed the same sights and I don't have any parts that wobble. Maybe be more specific.

If you are referring to the rear sight aperture(the little circle that you look through), no. If it is loose or unstable, you will have a serious problem with maintaining zero. Ultimately, no part should have free movement and if any part does, could result in unmanageable inaccuracy.

Wobble is not good. You might have something not tightened down or adjusted to far out?

I am not sure which part you are looking at. The rear peep sight may have a little side to side movement but should not be excessive. If you are concerned you should return it.

To be honest its a little on the noisier side. If u put it in an enclosed space or box it does eliminate some of the noise.

The neck rest seems to move forward with the head. Seems like a good thing though...I wouldn't want to cut off their air. Helps minimally.

Only the middle part vibrates. It's still functioning alright. Just not locking into place.

Hi, it is normal for it to wiggle for slightly. If the fitment is too tight, it would be hard to remove and re-insert. It should fit tight enough so that it won't slide around though.

I would say so, it has a slight hum once it gets going, but I wouldn't think it would be distracting.

With most in-wall units like these, I've found noise is mostly a symptom of poor installation. Failing to fit the unit in exactly right (using all the right foam wedges) will torque the chassis ever so slightly, or otherwise change the tolerances of some of plastic parts so that certain parts will buzz or rattle. A perfectly plumb, level, careful installation should allow your unit to hum along peacefully.

No... but there is a lot of tension in it already; I have put small books under the back feet to give it less of a slant, which increases tension a little. Silicone lubricant keeps it going smooth & cuts down on noise.

I had squeaking that sounded like it was coming from those wheels, but I did some research online and saw some people suggested loosening the screws on the pivot points just a half turn. I did that and the squeaking went away during the next workout (it took a few minutes but it did go away). I guess over-tightening them can cause squeaking where the pieces rub together. That's my experience anyways!

it does take a little pushing effort but i think it's normal and i don't adjust it often. the company would know better than any amazon purchaser. i would call them before returning it.

It does not vibrate a lot, but it does have a hum. Even that could be cut down a bit with some Styrofoam type padding along the perimeter where it meets the framing materials. I am extremely happy with mine. It was a return, so I got it for a discount, but I can't see why anyone would want to send it back.

There is an almost continuous creaking sound emanating from behind the seat where the sliding seat meets the seat track. It appears that the two do not fit snugly, even when the knob is tightened, leading to this very annoying sound. I've tried inserting a rubber wedge into the place where the track and seat meet, but it still doesn't solve the problem.

I do not have that problem. It is not stiff, but definitely not jiggly. You may want to return.

No, never had that problem. Sounds like you may need to send it back. Mines is not noisy. The fan is in the lid, but I have not noticed a real noticeable vibration and certainly it does not stop with the simple press on one side. Amazon has a very good customer service. Give them a call.

you could try getting a softer butt..... or maybe it's your butt thats making the popping/clunking noise? who knows lol

Yes, I do. At first I thought it was just a pesky piece of styrofoam stuck in one of the wheels, but after removing that it still squeaks. Only when I'm making forward strides though, not backwards. I haven't yet determined the cause or solution.

They don't make more noise, but I share your concern regarding excess load being put on the device because the head does not move freely.
