We all want to do our part for the environment, and one of the things that many folk out there are doing to minimize wastage is to reduce the amount of water used. You might not be confident of keeping track of how long you’ve been in the shower, and if that’s the case, the Water Drop Shower Timer is there to help you out. With its ability to attach to your shower cubicle wall, you’ll be able to monitor your time spent in the shower, and it can notify you when you’ve used up your allotment of water (thanks to the amount of time you spent inside). It’s currently going for $12.99, which isn’t all that bad. After all, if you save enough water, this device practically pays for itself.
