Annoying and not really adjustable
596580
This is an annoying design that cannot lock in a fixed position, consistently slides into two pieces and too expensive for what it is.

The cord is irritatingly too long, and the extender expands too easily. If you need them at the longest length (like if you have a long head) than it shouldn't be a problem but it's annoying always needing to adjust. And when I bend down, they slip a little off my head.

Easy to install, nice that it's adjustable.  However, the stand comes down at an odd angle that my son needs some practice with, plus it requires a little bit of muscle.  Those two properties make it very awkward - even for me, a coordinated 41 year old man.  Come to think of it, now that I'm writing this, I may just return it!

Bulky and irritating to wear, not a comfortable fit

Returned these because the strap adjustments were awful. Not like trx ones where you pull the loop up and down for easy adjustment. These ones are tough to move and it takes way too much time to get them to adjust evenly. The door hook also damaged one of our doors with light use, so we stopped trying to use that attachment. Overall dissatisfaction with the product has led us to believe that the extra money is worth it to get the real ones!

It is really large and clunky and the adjustable ear hook keeps falling off with makes it annoying while trying to work out with them.

Like other reviewers I thought this would be great in my closets and cabinets. However, it suffers from several design defects that make it highly annoying and ultimately unusable. For one thing the wires to connect to your lights is way too short thus limiting where you can place the sensor unit. In addition, the sensitivity of the item seems to vary depending on the type of surface it encounters. For example, it seems to register a cabinet door from a much shorter distance than it does a human. I had adjusted my sensor to the exact distance away from the cabinet door that it would just register when the door was opened. When you open the cabinet door and activate the sensor that part works fine but if you stand in front of the door even from several feet away it will sense your body and begin to flicker on and off very annoyingly. There is no way to adjust or position the sensor so that it either registers the cabinet door and/or a human. Since you open the cabinet and then look in it thus fails at its basic level. I ultimately replaced this type of sensor with a motion sensor which works much better.

Not really very adjustable. In order to change the adjustment, you have to get down and take it apart and put it together again. Which you will also have to do if you pick it up to move it, since the "adjustable" section simply falls out when you pick it up. Description is accurate but incomplete. Its redeeming feature is that it is as inexpensive as it is cheap. Works marginally better than finding a household item, such as a big book, to put under your feet. I'd return it, but it's hardly worth the hassle. My sister has nothing, and as this is better than nothing, I will give it to her and spend more on one that works better. (I've had ones from Fellows before, and they are greatly superior to this one. I'd wanted one that adjusted to a higher position than those do, which is why I ordered this one -- big mistake.)

Part of the problem lies with the fact that three quite  different Kensington footrests share reviews, so it's hard from the star ratings to tell whether one specific style is good or not, and trawling through all of the reviews trying to find the ones that match the product you're looking at is onerous, to say the least. Perhaps the other styles are better for my needs, but I don't want to hunt through the reviews finding ones that pertain to the more adjustable product.

It says it is adjustable, but when you try use it in the smallest setting, it forms a weird crease that won't smooth out due to how it's made.

The adjustments are finicky and when the best and hips are big the neck won't stay small. Its a little wobbly on the stand too

It looked exactly as pictured, which is adorable.  However, the fit leaves a lot to be desired.  The clips for the straps aren't properly placed, so it pulls extremely tight, even when you adjust the straps at the side.  It wouldn't matter about the size of the person in the vest when it comes to fitting properly.  This vest simply isn't produced in a way that allows it to be properly adjusted.  I'll keep it in the back of my closet as a backup option, but I'm purchasing a different vest for daily use.  This one just doesn't work.

The volume and selection of song should not be on the same button .. Hard to adjust the volume and it keeps changing the song.

It is not adjustable :( and i do not feel comfortable when i wear it probably because of the Mic not sure.

I had this product for about a year and was constantly adjusting it.  Then, I bought a much less expensive one because this one was just so big and kept tipping over (the plug extends from under the antenna, and it is unstable, both contributing to this big, bulky thing tipping over so much.)
I am so much happier to have regular bunny ears, they work better.

Not intuitive , not easy to unclip , feels awkward

Moves more than I would like but its certainly tolerable. When fully lowered the second tier does not work as the support bar is too short. Also the height of the second tier does not adjust. It cannot keep the rubber pieces on when the second tier is installed.

Really wanted this to work out better.  But there are several issues:  1)  in order to adjust it, you really have to take your computer off, and look at each of six dials while you do it.  If you don't look, it's almost impossible to get it so that both sides are even and it sits straight  2)  It's not wide enough for me to use with my legs crossed without having the table legs awkwardly hitting my own legs - sitting cross-legged is one of my main sitting positions, and why I wanted a lap desk to start with  3)  The legs are also so thick, that it forces a big gap between me and the edge of the furniture, so I can't use the armrests on my chair  4) the stopper is high, and it cuts into my arms while I use it.
