Poor product

Have had safe guards for a few years. Constantly working on them, 4 new sensors this spring, 1 died in 3 days. Have 2 more out within 3 weeks. Service is good, fast and timely repairing, but the product is poor. No reimursement for diagnosing and shipping of defective products.Read reviews, most praise the service and repairs, but very few say its a good product. Will be looking for something else to replace, and will not be recommending to anyone
