Thank you for your detailed and thoughtful comments. Obviously you put a significant effort in your Garadget setup and it's unfortunate that it haven't yielded a desired results.
I'm very much able to say that that a small percentage of devices fail, and we do everything to minimize that number including 100% testing of all units sent to Amazon inventory or directly to customers. It may not be your case, but from the previous experience, the majority of the issues reported by customers are not caused by the faulty hardware and resolved in the course of the technical support similar to what you've experienced.
It's in the consumer's power to choose to request the replacement at no cost or return of the unit for any reason. However the majority of the returned units from customers who never reached out for help found to be performing to specs and pass all of the functional tests.
The claim about ease of the setup is relative to the alternatives in the same category. Obviously it takes some effort to get the unit connected to the opener, but it doesn't require running long wires to the door and it doesn't involve the intricate reed sensor setup. Although it wasn't your experience, there are numerous reports of Garadget setups completed in 10-20 minutes. Even in the wake of a highly damaging backlash against the product for the reasons not related to it's features, Garadget currently retains a higher customer satisfaction rating than a competing option from an industry giant.
I agree that disclaimer may be necessary to point out that the app can provide the accurate reporting of the door state only if setup was completed successfully.
I would like to thank you again for giving Garadget a fair try, for your valuable comments, suggestions and well wishes. We'll continue working on the product improvements and hope that at some later time you will reconsider Garadget for your remote monitoring and control needs.
