I bought this for an employee that I scared everytime i walked up behind her (at her desk) and rather than being responsible for her demise via heart attack I thought I would try this mirror out. It clips right to the to of her monitor and now she can see me coming a mile away!!! The mirror itself is a little small but it has certainly fixed my problem with my employee. Thanks for keeping my workforce alive!!!

This mirror fits on the top of a monitor well but it is best to clip it to the corner so it does not interfere with viewing of the screen. It is big enough that you can catch movement behind you but not so big that you see everything. It met the need I was hoping it would...a prompt to turn around and greet someone entering my cubicle.

Moved to a new building for my job. Where I now sit is in a heavy traffic area, so I have people coming up from behind me off and on all day. I have a "thing" about people behind me, so this has fulfilled exactly what I needed. I shopped around on Amazon and was glad to find one that clipped AND had double sided tape. I use the clip so I don't damage company property and so I can take it with me when I retire. Like other reviewers, I thought it was pricey for a little bit of plastic. There were cheaper choices but, again, this fit the bill better than others.

The clip on this mirror is made in such a way that if you can clip it somewhere other than your monitor it would probably be best. I unfortunately don't have another location. Because of how long the clip part is I have to put it all the way to the corner, which is fine, just so the clip doesn't hit the screen itself, but it's wider than the edge of my monitor so it does block the screen a bit and slides around on occassion. The only issue with having to put it all the way in the corner is that it weighs my monitor down just a bit, so my screen tilts a bit to the right (but not a lot) instead of sitting square and upright. If you're not using a mounting arm but have a more stationary monitor, then this shouldn't be a problem. It also can slide around sometimes and ends up crooked or knocked to one side, so I just have to readjust it once in a while. It works well though, and has a nice pivoting ball joint so I can angle it just the way I want. It allows me to see down the hallway behind me to see who's coming, which is all I needed it to do. I only knocked one star off because of how it doesn't stay securely all the time and tilts the screen with it's weight. I think if the clip part was a little skinnier to account for the fact that it has to sit in the corner of the monitor and maybe had some rubber grip to keep it in place instead of just the plastic grooves that don't grip to a plastic monitor, then it would probably be 5 stars.

All in all it does the job and for a pretty reasonable price, by far the best quality of the mirror itself and not warping or being distorted like I've seen on most of these types of computer mirrors.

This is the perfect size to see people entering my cubicle. I hate sitting with my back to a doorway, but I have no choice. This was the perfect solution. It is smaller so it isn't distracting when people are just walking by. It clipped right to my monitor with no issue.
