does the half hour one work well?

In my opinion, those work better than the 2 hour strips. They do about the same whitening, it's just that you don't have to go through having them in your mouth for 2 hours

They are good but not as great as these and don't have the adhesive and slide around a bit. This one is definitely worth the extra money and time. I don't smoke or drink much coffee so they brought my teeth to a bleach-white.

I have used it for over 25 minutes and had no issues! I handle may get a tad bit warm I believe it all depends on how high you have it running and if you are using the black box it comes with. I use it on high with the box set at about med and have had no issues! You will enjoy ever second minute hour or marthon!

My wife and I play a full game in about 2 1/2 hours. It is not a quick game, but it is fun and well balanced. The set up of the game takes a bit of time, but once you get going, it moves well.

Depends on what timeline you choose. Mine lasts two nights as I do 15 seconds on 50 seconds off.

Mine works just fine. I constantly just hit the time button 8-10 times and when I wake up in the morning it is still turned on.

Hi Abigail.I have never used it for that long Probably about an hour- so it has been OK.

No, iy has 17 on-off cycles a day so it is not enough for one every hour, and the minimum on time is one minute. Good luck

I used it withiin aobut 6-8 hours after opening it and it worked just fine. I saw virtually no difference between the first night I used it and the second. I really am glad that I purchased this item!

No it should not matter if the 6 hr setting functions exactly the same way as the 5 & 15 min timers do. Most likely it does.

I think it will work for as long as you have it on. I have not traveled over 3 and 1/2 hours with it on but I think it would keep right on working.

I have found this can vary but for the most part with a half pot the first hour loss is about 45 deg. With a significant slower loss after that.

What I noticed is that machine will not work more than half an hour if I use continually, as I shred only once in a month. It need a good couple of hour cooling time, may be something wrong with my machine.

Half an hour like others have said. The 18 hour estimation is probably spot on but it's always surprising how long it really lasts. Have used it intermittently for the past few weeks since I bought it and it has worked well. What is nice is that you can end your music and forget to turn the switch to the off position and the device will automatically turn off after a few minutes. Normally I just leave the device in the on position and tap the button on top to resync when I want to use it.

i don't always do it but it still seems to work. i try to get it down 20 to 30 mins before.

It does 1, 1.5, 2, 3, 4 and 6hr. I have 3 of them, all flawless performers. I use them every day in business.

Yes, indeed it will work for about 6-8 hours. We can change the frequency from 1 minute to 3 minutes which should resolve your issue.

I have not actually timed it. It is very good in my opinion - I think it varies some depending upon what you are doing ( how hard you're working the computer). I believe that it is averaging 4 to 6 hours with pretty steady use.
