Great reminder device
I ran across this as great ideas you had not heard of.  I have a goal of drinking 150 oz of water a day to lose weight.  After reading reviews and seeing videos I just had to have one to remind me to drink to meet my goal of one bottle every 1.5 hours.  FYI, the rubber bands are how many more bottles I need to drink.  I remove one for each one consumed.  The price was a little high I thought but have found it works well.  I was concerned after reading some reviews where the device can easily come off the band and be lost.  I have been very careful to just use it inside or only outside when walking on the drive.  After over 6 months of use, I have not found it detaching from the band.  Just be sure it is clearly in your line of sight to get your attention when deeply into a project.
