drains batteries fast

its very bright and good for the price but the batteries go dead so fast, got really good batteries and went dead within 3 weeks of minimal usage (just turning it on to see when I go to the restroom at night). Just a warning to people that get this problem, when the light starts flickering and acting like its a bad connection and you tap it to make it brighter, the battery is going dead. change the batteries out and you will get it back on normally.

We got this to use with Smartthings as a panic button for an elderly grandparent. Works fine when the battery is new, but for some reason it eats batteries like crazy. Usually within a week or two the battery would be dead. And this was without ANY button pushes whatsoever in between.. Cant imagine how quick the battery would go dead if someone was actually pushing the button. In the end there was no way we could count on this thing to be available in case it was really needed. According to the Smartthings website, this thing has "fantastic battery life". Well, that is a bunch of baloney. We have several z-wave devices that go for two years or more before requiring a battery change. This one is absolutely ridiculous.

Works great. Eats up batteries pretty quick too.

This control only uses AA batteries and will drain the batteries rapidly if left set on the "ON" position.  The remote will also go up/down like 10 times when you press it once at times.

I really liked these for my weird sleeping habits. They run through batteries way too fast though, so I DO NOT RECOMMEND THEM!

Quality flashlight but drains battery very fast and that type of battery is expensive, I suggest to buy AA flashlight instead

It eats the batteries way too much faster than normal.
It's only recommended for night-time use.

Not quite a year and the unit is repeatedly draining fresh batteries over the course of a week.

These undercabinet lights look great but run out batteries very quick even when you don't leave them on for long periods. Won't be purchasing or recommending them.

Kills brand new batteries in only a few weeks. Going to return for new remote.

Great value for the price ($23 for base model, $29 for the one with charger & batteries). But the unit uses a lot of batteries and barely holds for one day after fully charged. Tons of work to charging and swapping batteries everyday.

I bought both models and wish I bought both sets with charger.

Outdoor communication is OK, Once there are some distance (less than .5 mile) and some buildings between, these units would not work.

It works but the batteries don't keep a charge for very long.  I find that after about 45 min I am already needing to charge the batteries again.  Also if I don't keep the controller charged when not in use the battery drains as well.  I figured three stars was more than enough since the product does work, just not very well.

Battery drains too fast. not  enough battery life. I can only  use it for about 15 minutes before it does down and dies. Then i have to recharge it which takes at least 8 hours.

This is adorable and makes the perfect light, but unfortunately I never have it on because it uses batteries too quickly. It came with 6 batteries (uses 3 at a time), and I burned through the batteries and spares in under 2 weeks. I got it hoping to leave it on at night in our bathroom, but that is just way too much "on-time." It's also not so simple to change the batteries, as you need a tiny screw driver to do so.

It would be much better if you could just plug it in.

My kid likes this phone, but it eats through batteries like you can't believe.  It takes AAA's.  It does NOT go into power saver mode if left on but not played with.  Even if it is diligently shut off after playing, the batteries STILL need replacing every week or 2.  To be clear, my kid only plays with it for about 5 min a day, so replacing batteries so frequently is ridiculous.
