Product Description

Amazon.com Review

Save valuable time and simplify your watering schedules using this Gardena electronic water timer. This compact unit attaches directly to your outdoor spigot and allows you to program up to three daily watering periods lasting from 1 to 120 minutes apiece. The timer's reliable electromagnetic valve technology conserves energy, making this unit efficient, as well as practical. Programming is performed using two simple dials on the unit's face. To make things even easier, the program unit can be removed from the computer with the click of a latch, allowing you to do the programming from the comfort of your home. The unit requires one 9-volt alkaline battery (not included) and includes a one-year manufacturer's guarantee.

2.0 out of 5 stars OK, but pricey for what you get, April 5, 2002

By A Customer

This review is from: Gardena 31805-4 Electronic Water Timer (Lawn & Patio)

I own about 20 of the 31805-4 and 31820-4 Gardena timers. All of them have worked for at least 12 months, but many have failed within 24 months. I don't like having to buy more of them, but there's really nothing else available. One additional "problem" with the 31820-4 is that when you choose longer watering times you must also choose longer periods between waterings and when you choose shorter watering times you must also choose shorter periods between waterings--in other words you can't choose short waterings with long periods between.

I had tried to save a little money and bought another timmer... well it leaked so badly in the guts of the timmer.. not the connections, that I had to return it and then I bought the Gardena 31805-4 well... no leaks and everything is now watered through the timmer! Could have saved alot of time if I had just bought the Gardena first. A very happy customer!

I have 8 timers working on our property and I am starting to convert to Gardena T-1030 for replacement. I have one working now and it has been functioning for close to a year.
Down here in the tropics, a well designed and constructed piece of equipment is importand to withstand the UV rays and the weather. This product fits that requirement.
