Tends to go sleep after several days and will not wake up with remote.  Had to reboot it 3 times to get it working again.  One more time and I will need to return it.

Works but "goes to sleep" too often and not very sensitive.  If my laptop had more USB connections I would use a USB mouse.

I loved the case at first, and for under $10 it was a steal.  The stand works great in horizontal position, not so great in vertical position, but that's ok.  Sleep/wake capability has failed after 5 days of use...bummer!  Would have been a much higher rating if it was still functioning correctly.  I did read that others had this issue as well, but thought I'd take the risk for the price. EDIT - the sleep/wake has started working again so I'm giving a higher star rating.

Nice look and feel but tends
to become tired very quickly.

Not enough support for the daytime but works well for sleeping.

The mattress topper is slept on by 120lbs, 3 nights a week for 10 months. After a few months a nice dip began to form, so I flipped my head to my end and my feet to the top to help get away from the dip and let it come back up. That did not work. Now, I just get stuck in the dip and stay they're all night- making the problem worse. Yes the first few months this was very nice. But it's not anymore and hasn't been comfortable to sleep on; causing server back pain. I'm 26. I shouldn't be experiencing server back pain. Nice product however it does not hold up. This has not been folder or misused. It's on top of a mattress that I only sleep on 3 days a week.

It keeps going flat.  You can sleep on it then the next day it goes flat.

The alarm is not predictable as far as going off. One day it is fine the next day it does not make a sound. I did like the size, shape and color but it is not worth much if the alarm is not predictable

The wireless trackball goes to sleep after a very short time of inactivity. I find it very distracting when using the computer. It makes a noise each time it reconnects and there is a short duration that the pointer fails to move in response to moving the track ball. Sometimes, I have to click a button to get it to reconnect. I called Kensington support and was told this is normal for the wireless track ball and does this to save battery. There is no adjustment to the time of activity that triggers sleep for the track ball. Had I realized this, I would have bought the wired version.

The sleep feature doesn't really prolong battery life. The cursor jitters when it is left alone, you have to make sure it is still so the mouse will turn itself off. One nice thing about the sleep feature is that I'm not interrupted by my computer monitor suddenly showing the play bar when I'm watching an Amazon video. Hard to get an exact placement for detail work.

I put one of these in my bedroom.  Before installing it, I tossed and turned a lot at night and rarely dreamed.  Now I sleep deeper and dream more often.  I suspect my allergies were interfering with my sleep before. (I am primarily allergic to cats and dust mites, but also have a mild mold allergy.)  The blue light on top does not interfere with my sleep, but sometimes I turn it off anyway.  There is a small blue LED on the side that does not turn off, which I found annoying until I rotated the unit so that the LED does not shine in my eyes when I'm trying to sleep.  The unit does not make any noise (the air is moved by heating, not by a fan).

Before buying this, I needed 7-8 hours of sleep per night to function well during the day.  Now I feel the same on only 6-7 hours of sleep.

The product literature claims this can help remove odors from the air.  It may reduce the pungency of odors, but it does not remove them completely in my experience.

HEAVY - and does NOT have auto wake-off feature as stated. Yeah, it's cute but it adds SO much weight and thickness to the device that I'm not sure I'll continue to use it - and it certainly does not turn it on/off as promised.

It took a few days but this has been working for us consistently for weeks now. The nightlight feature is great but it does wear out the batteries if your kiddo keeps it on all the time. I ended up putting it on a shelf out of reach. Its so nice to be sleeping past 4am these days!

As others have mentioned, this topper needs to be aggressively fluffed at least every other day to keep it from packing down and getting ridges. If you get lazy and leave it a week it's much harder to get the feathers to fluff back out again. It helps my cruddy bed but we still get back pain so it's by no means a miracle fix. It doesn't appear to make the bed any hotter though which is good. overall good quality construction and very pleasant to sleep on when freshly plumped.

Doesn't stay up, looking for other ways to make it stay

I bought this for my son because he has developed a fear of the dark. When his "magic lamp" arrived he was so excited. Unfortunately we can get it to stay on through the night. We have followed instructions on charging and it just doesn't last but a few hours.
