Just what I was looking for.
Batteries don't last very long

Update: I've seen about a month of battery life with regular use from this. Not as good as I would have hoped, but replacing the batteries is super easy.

I ordered this for the toe kick on a 4ft bathroom vanity. I thought having a motion activated night light would be great for those early AM trips for our guests and visitors. The LED strip has a double sided tape backing which makes installation a breeze, however the tape sticks better to the vanity than it does to the LED lights. It's a minor annoyance, but something that should be noted. The kit also includes a 3M double sided foam pad for installation of the battery/motion sensor box. The box itself is about 1.5" wide by 4" long; which should be small enough to tuck out of sight (but still within motion range) in most applications. The amount of light emitted is great, and allows me to see in the dark bathroom despite having the LED pointed at the floor below the vanity. If this was mounted in a more visible location it would provide substantially more illumination.

The only two minor complaints I have are with the timer and the motion sensor:
First, the timer is just a dial with about 270 degrees of travel, however the first 120 or so don't seem to make any difference. It seems to go from about 10 seconds, to 60 seconds with no adjustment in between. Maybe if I fiddled with it more I would have some success, but I found a setting I liked after a few tries.

Secondly, the motion sensor at times is too sensitive, and isn't sensitive enough. I have mine positioned so that when the bathroom door is opened or someone steps into the bathroom, the lights will turn on. I find it turns on immediately about 75% of the time. The other 25% there is a delay in activating the light. Not troublesome, just annoying. Other times it seems the motion sensor will pick up phantom motion, or motion in the hallway, which is pretty much out of view of the sensor. I'll walk by the bathroom and find the lights on from time to time.

I've had it installed for a few weeks now, and I'm using 4 rechargeable AAA batteries to power it. The lights are still going strong, I'll report back with anticipated runtime when I have more data.

I purchased this for my elderly mother's night trips to the bathroom. I put one along the metal bed frame and one along the bottom of the bathroom vanity. She doesn't need to turn on the lights as these are bright enough. Just have to stock up on AAA batteries or use rechargeable batteries as you do go through batteries fast.

I have this lighting my safe and it does a great job. the motion detection works well & the amount of light is good for my LARGE safe ( 48 capacity cannon safe). would give 5 stars but the adhesion on the tape only lasts about a week before it starts to come loose and the tape light tape begins to droop. Keep this in mind that you WILL have to seek other options to mount the light strip.

There's a lot of choices for these on amazon so I had to do my research. These seemed to have the most options, but do they work well? Yes.

Options to have a vast choice of "duration time" for the LEDs to be on was what sold me. I have other units like these but you're stuck with one duration and I have another one where you only get two choices. This one has a dial with a ride range of your choosing.

Also, this one allows you to use either batteries OR plug it in via USB to a power outlet. Basically, you take a charging block (cell phone) and plug the USB in. Note: I used it via battery at first but I found that since the strip is so long it drained the batteries within a couple of weeks. That didn't work for me so I plugged it in. With that said, I have it in the kitchen under the cupboards and the motion detection is out of this world sensitive, which is awesome. I mean if you get anywhere near the kitchen it turns on. This is why it drained it so fast, and because I had it on a long duration.

There's also a setting for "always on", or "dark only". I use it in the coffee corner above the coffee maker so when I wake up in the morning I don't flood my eyeballs with bright kitchen lights. It's perfect.
