Description
Rain Water Alarm System projectRain Water Alarm System is a practical electronic safety and monitoring project designed to detect the presence or rise of rainwater and provide timely alerts.

Not recommended
Scent: Earthy, Nutty, Refreshing, Size: 4.06 Fl Oz (Pack of 1)
Not the batana oil you should be buying. No this isn’t the one. Definitely don’t recommend it. It has no that coffee smell of the real batana oil and has extra chemical ingredients and makes it runny almost like a liquid oil. I made a mistake buying it.

Has no oily scent.
Scent: Earthy, Nutty, Refreshing, Size: 4.06 Fl Oz (Pack of 1)
Just started using it. Smells like oil not over powering. The quality is rich and it’s not runny oily. For the size of it’ll last couple months. Worth the price.
