Great product that I can sadly no longer purchase on Amazon. Fast shipper, great packaging, and stellar performance thus far!
The teckin products are very reliable. Love how they work with Amazon Alexa.
I found it difficult to setup. I just kept trying and it finally worked.
Teckin SR41 Smart Light Switch
All of my Teckin products have worked 100% perfectly. Easy WiFi connection with continuous service. Has not lost connection like my other system.
