Batteries don't last long

Batteries don't last very long (about two or three months) even when the laser is not used or even turned off.

The candles look nice and the remote control is wonderful, as it allows for not just an on off function but also a 4 or 8 hours setting. However the batteries did not last very long. If I had to guess I got about 50 hours of use before I had to replace the batteries.

I bought these for use in a camera. After a short time I went back to using alkaline batteries due to the short battery life.

Pro's: Batteries are rechargeble, multiple times...

Con's: Batteries don't hold a charge for very long...They don't last. They let me down at the wrong time for me.

The light is nice and bright when the batteries are fully charged; however, for an LED lamp, the batteries (included) don't seem to last too long.  Only a few weeks in and it's too dim to be usable.  LEDs ought to be more efficient in this regard.  However, we bought mostly as a toy for our kids and they still have fun with it, so 3 stars for accomplishing what we had hoped!

I like them and they lasted a good while, They are not as bright as I thought they were going to be.  Mine came with batteries already, so it saved me time to go buy some and it showed me which ones to get

I love this set, but the light doesn't last as long as I would like on a set of brand new batteries. I have it on the timer setting, and they last maybe 2 weeks at full brightness, then have slowly started to dim in the last two weeks.

Most of the batteries were burned out and there is no way to replace them (without some DIY work). Overall they are nice, but don't expect them to all work - at least not for long. They still make nice bathtub toys, but the lights were the best part so....

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

Lights are very bright however the rechargeable batteries don't last more than 4 hours. Then it takes overnight to charge them.

Lights are great, exactly what I needed but they don't last very long as far as battery life.

The batteries charge up fine, the compact size is great, the power of the batteries doesn't seem to last very long.

When it works, it's great. But my batteries have only lasted one week, tops, on average. Even with very fresh batteries! Disappointing, even if I got it at Wal-Mart for $15. Get another light.

The batteries on constatnly running out. My kids like to leave them on so they can talk from different rooms in the house. They're 8 and 5 and have a lot of fun with these radios, however the battery situation has left me wishing I had purchased recharable units.
I'm not sure if it's specific to this product or all two-way radios, but we also get the occational 'phantom' voice that comes across. Freaks my kids out.. and of course I egg  them on to keep them guessing.. :)
But the batteries. Seriously.

I really like the concept of battery operated tools, especially for my boys who do work around the neighborhood and I don't have to worry about them using corded tools w/electricity. But the life of the batteries is terrible: 10-15 minutes each. Unfortunately, I didn't realize this until three months post purchase when it was too late to return the tools so I purchased two extra batteries - now have SIX and hopefully my boys will be able to juggle the batteries around to make some money to put in their savings account and a little fun money too.

They work fine when you put the batteries in, but they seem to have a constant to have a drain. They chew through batteries when off and don't work when you need them too. Kind of a pain to change batteries, even if you had them with you they would not be convenient enough to do on the side of the road.

Batteries didn't last long, and not enough adjustment in the guide.

My kids are 3 and 5 yrs old and love them, but they don't last long.  After the kids are playing on them off and on for approx 2 hrs the battery dies down.  This is frustrating because you have to charge it for 14-18 hrs.  I did buy an extra battery for $50, which helps, but it is still disappointing that they don't last long.  We did have an older model of this toy approx 5 yrs ago and the battery would last several days.  What a disappointment.  I thought products were suppose to improve, not decline!!
