Good for the price but has balancing issues

Decent for the price.  Only issue is there is no adjustment for the gimbal centering and as a result it's impossible to get this truly balanced.  It can be balanced great for one orientation of the handle, but as soon as you change it the balance becomes slightly off.  Still, I'm able to get very good results for a while before having to re-balance.

I tested the headphone right out of the box (which by the way was squished and dented). The sound quality was great - clear and crisp. But it seems unbalanced, like the sound on the left side is lower than the right. Also, if I bend or twist the jack I can hear static noises, like it is not completed grounded. Overall, it is fine for the price since I'm not going to move the jack during my commute and music is just white noise for me.

A little unbalanced - I had to mess with it a bunch to make sure it didn't fall over once I had added the mic. Does what it's supposed to do though.

The quality seems good enough and it is for the price, but it does move around more than I'd like.  With the base weighted down, it still swivels with a good wind and I'm not sure if there's a way to prevent that.  We did have a heavy wind pull it over a bit when I apparently didn't have enough weight on the base and the long leg of the base bent up slightly.  Otherwise, it seems to be fine after the first couple weeks with it.

When you compare this to other camera stabilizing products out there, you'll see this one is very inexpensive.  When I took it out of the box I was reminded that I chose the cheap competitor.  You essentially need two things with a stabilizer:  a gymbal to allow the system to move, and the ability to balance the system so it won't wiggle and tilt.  This product has problems with both of these:

The gymbal:  The gymbal on this product is not super-smooth, it drags.  A good quality gymbal will allow the system to spin for a long time before eventually slowing it to a stop.  This gymbal allowed the product to spin less than one turn when I tried it.  That's a lot of drag.  This means the camera will be turning everywhere my hand turns.  Also, the handle has about 10 degrees of movement in any direction before it hits the housing.  So the handle must be held pretty much straight up.

Balancing:  Balancing is very limited.  There is no left-right adjustment on the camera mount.  There is one weight provided, about two pounds, that you can slide up and down along the midline.  If your camera is not two pounds, you'll have to use something else to balance your camera.  Luckily the weight is easily removed.  A bolt, wing-nut and washers may do the trick.  Mark the position your camera is in once you have it in balance so that you can save balancing time next time you attach it.

Pros:

1. It feels very solid, and with some tinkering and good luck, it can be balanced.  Tinker with the weight, and be patient.

2. The price is very low.

And so:

It will never give you the super-smooth shots we see on youtube where the cameraman is running but the camera is getting smooth shots.  But, the price is very low and they don't say you get what you pay for, for nothing.

This is a good product for the price. It's lightweight but feels stable and is very easy to install - just set the height of the shelf and secure it to the underside of your desk with 8 screws. A few things to note, though:

1) I didn't measure my keyboard and mousepad beforehand, so the shelf wasn't as wide as I expected. If you have a full-size (104- or 108-key) keyboard, you most likely will not have room for a full-size mousepad on the tray, hence the mini-mousepad provided. If you're a gamer and need a standard or oversized mousepad or gaming mat and also have a full-sized keyboard, definitely buy a wider tray.

2) The supplied mousepad is very flimsy and thin. Luckily, it's removable, and mousepads are cheap. The wrist rest is actually decent, but can also be removed or replaced.

3) The 8 screws provided are ok, but if you want a more secure hold, I'd highly recommend using wood screws to attach the tray to your desk. Depending on what your desk is made of, you may want to drill lead holes beforehand.

Also, while it's possible to install this alone, it helps to have a second person hold the tray in place while you're making marks for screw holes and screwing it in.

I love that you can fit any tripod on here and it even holds a fair amount of wait. But the wheels are so problematic. For the price, I'm going to overlook it and still use this. But this is just a warning to all future buyers - the wheels will flip around when you change directions, causing a noticeable jump in the steady movement. Moving one direction it works fine and looks smooth for me. If there is any shake, it can be easily softened with a stabilize effect. But any slight change in movement causes the wheels to flip and it affects the footage greatly.

I would say this is an okay value for the cost. Not the easiest to adjust so the sides are balanced. I would also not place anything too heavy on it. The monitor we use it for is about the limit for it.

This is pretty cool, but not perfectly balanced.  I guess to be more accurate, it's not balancing the weight, but more about the strength of the magnets (which I would imagine would be very difficult).  As is, it does spin for a while (smoother while spinning fast but wobbles as it slows down).  You can tell that the magnets are not matched perfectly because while still, it always rests in the same position.  I would imagine that some lucky people (out of coincidence) have perfectly matched magnets and it will spin for a crazy-long time.

I received this stand as a birthday present a few weeks ago. I've since gotten some good use out of it. Overall it is pretty heavy and seems well built for the price. The grip heads included seem particularly well made. The turtle base as well is just fine. I have had an issue however with the riser. Only the bottom most section of the riser can be raised and tightened into place. The second segment of the riser will not tighten down even with the thumbscrew all the way tightened in. It doesn't seem like the included bolt is long enough to press against the smallest top segment of the riser, so I can only extend the stand to about 5' tall. It's still useful as is but I wish the top segment of the riser worked as the stand would be a lot more versatile.

Also, while the arm is only 20" long it's still pretty useful. I really do not understand all the people who are buying this stand which clearly states how long the grip arm is, and then complaining about the length of the grip arm.

This is good for the price but i find the top leg part akward and its not as stable as it should be.

Does what it needs to do but has its flaws.  Tips over pretty easily unless you are perfectly centered over a leg.  More annoyingly, it seems to slide despite being locked at the bottom, and every day or two needs to be unlocked, readjusted, and locked again.  Neither of these are deal breaking, just annoyances.  But hey, its a $20 stand and does what it has to do.

In general this is good but it may be not really smooth to adjust the height of it. Also you have to manually keep adjusting the angles to make it balanced, which is a little bit inconvenient.

I bought this for my fiancee to use with her digital piano and it works well enough for lighter books and sheet music however the extending piece on top can not hold the heavier Joplin music book that she bought. The piece that's supposed to keep the upper part extended slips and the stand goes down to half size -- not very good.

So this stand works well enough to hold lighter music but fails completely with heavier music books. For the price though, works decently well.

You must "balance" the weight or the unit tips.  It works fine with a lot on it but with only one or two heavier items it does tip to one side and you must adjust the weight so it turns easily.  It looks really nice if that means anything?

Did get it quickly with Prime but I DO NOT RECOMEND this item.

A good weight bench costs a couple of hundred dollars minimum. I give it 3 stars because it is as good as one should expect for the $89 I paid for mine.

The supports are very narrow. This causes 2 real problems. First, the supports are right where most people want to grip the bar. And second, with even a 5' bar you need help to swap out large plates. If you take one plate off, the opposite support is close enough to the middle of the bar that it will tip under the weight on the opposite side of the bar.

It's flimsy too.

All of that said, I've been using it for 3 weeks now and it gets the job done. I've been doing presses, leg curls, extensions, etc. and have been getting some really good workouts in.

i like the fact that it's portable. However, even though it has some weight to it, it doesn't balance by itself.  I use it on top of my bed and the minute i move the desk falls over with my laptop. It has to precisely aligned and you can't move. Then at that point the desk stays put.
