Excellent hydration assist device
This little gadget has been a hydration life-saver. This flash is very bright and eye catching even if you aren’t looking at the bottle. The flash grabs your peripheral vision. It flashes every 30 minutes. It will reset the flash time interval to 30 minutes again when the bottle is tipped as if your drinking. So, keeping it set on a flat surface is important for accurate timing. It does not flash constantly after the 30 minute time. It flashes for as minute or two then resets again. This is handy for when you’re sleeping and protects the battery life.<br /><br />For best results, keep the device facing you so your peripheral vision will catch the flash. It’s safe to be placed in the fridge if you’re going to be leaving it in your bottle while you leave the house or go to bed. Not freezer safe. The silicone band is very accommodating to bottle size and shrinks back to shape quickly when coming off a larger bottle and going back to a smaller one.<br /><br /> I wish it also gave audible cues but it has turned out to be more effective than I thought it would be just with the flash. Highly recommended for anyone who struggles with adequate hydration.
