batteries run out very fast.

I have found using the rat zapper that the batteries get used up very fast, a few weeks at best, even without any catches. The D batteries that it uses end up costing quite a sum after a few months.

 If you need it for mice, there are much smaller devices that do the same job using a lot less electric and take up much less space.

It has an electrical malfunction. When the batteries are put in, the batteries and light instantly get extremely hot. Way too dangerous. Very disappointed.

Really cute. I only turn them on for very short periods of time. The batteries die way to fast.

The product is ok, but batteries have a very short life.

Batteries discharge quickly, get hot and swells in thickness! Could be risky to use!

The batteries die really fast but they send you 4 and it only takes 2 at a time so it's long enough for you to line your sights up. I was  surprised how fast it dimmed.

The light from the window candle is rather orange for our taste; it's not quite Halloween, but it's close.  However, the biggest issue is that the product burns through AAA batteries very quickly.  Using them on the product's 6-hour automatic built-in timer, we had to start replacing batteries within days of first use.  It's just not cost effective, or environmentally conscious.  We intend to return these and buy candles that run on AA batteries so we can at least use rechargeable batteries.

the batteries in this die too fast for it to be any good. I don't know why they die so fast but we have it in our little car games bag and every time my son pulled it out the batteries were dead. at least our L-max works great. We just haven't been able to get much use out of this product, and I think we overpaid for it because of the battery problem.

Cute but burns through batteries really fast - if I'd known, I'd probably have gotten one that plugs in.

The batteries doesn't last for long, maybe 3 or 4hs max.

It's a really good little flashlight, but it goes through batteries more quickly than any other flashlight I have ever owned.

the batteries lose power fairly quickly, and it's slightly disappointing. i have switched back to my battery operated pack. i did not like them.

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.

does the job as advertised but the battery run out really fast after using it 10-15x the battery kind of die and got to change it.

These are very cool but don't last long at all. I haven't had mine a month and already have had to change the batteries three times! Thats redicoulous!

I really wish I would have paid attention that this could not use a rechargeable battery or be charged via USB or something. We have never actually been able to use it for more than a couple of minutes, because the batteries run out super quickly. I got this for my son last year and now I'm looking to replace it this year.

This spotlight is very heavy, but on the other hand, is extremely bright.  We live in a subdivision where there are no streetlights and when we walk the dogs at night, we want a bright and "wide" light.  The problem was, the battery ran out in a very short time, and you must dismantle the whole unit to change the battery.  Also, it is difficult to find exactly the right battery and Coleman doesn't seem to carry replacement batteries.  Our unit has been sitting in a box for about a year and a half.  I certainly would not buy another one.
