What reviewers found
Irrigreen Smart In-Ground Sprinkler System 3
- Bob Vila (4/5): A grid of 20 cups over 5 days showed near perfect coverage with no measurable difference between circle and irregular patterns; couldn't schedule beds and shrubs separately. Source
- TechHive: Each rotation put down about 0.05 in over roughly 8 minutes and throw reached about 30 ft, but a stream tuned to stop inches from a path oversprayed about a foot the next day. Reviewer would not tear out a working system for it. Source
OtO Smart Sprinkler
- Bob Vila (3.5/5): A month of testing in southern Ohio: easy setup, ran daily at 6 a.m. in hot weather and skipped watering during a rainy week. Source
- The Smart Home Hookup: Three cup tests averaged 47 percent distribution uniformity, with some spots getting over 4 times the water of nearby ones; a quarter inch run took 1 hr 48 min. Reviewer said it fundamentally fails as a sprinkler. Source
