Extremely Disappointed – Poor Installation & Badly Trained Technician
I bought the LAVNA LA5 WiFi Smart Glass Door Lock expecting a hassle-free smart lock solution for my glass door. The product specifications clearly state it’s for 10-12 mm toughened glass doors only, and that there should be a minimum 5 mm gap between the glass and the frame. Amazon India Here’s how reality turned out: Even though my glass door already had a 5 mm gap, the technician installed the lock in such a way that it collides directly with the glass every time the door is closed. When I complained, the tech’s solution was basically to tell me to call a glass fabricator to increase the gap — something I shouldn’t have to worry about if proper installation was done. It seems the installation person was not trained well enough to understand how to align the lock with existing door setup. Instead of adjusting the lock properly, they passed the burden onto me. Overall this has been very frustrating. The idea & features of the product are good, but what matters just as much is installation — which here is badly botched. If you have a glass door and expect things to fit out of the box, this product + service falls short. I cannot recommend this – you’ll likely have to spend extra time, effort, or money just to make it work properly.
