Hello Jarvis Jin!!! I watched your video, thank you, it was very interesting, I was especially interested in how you tighten the coupling bolts through the handle, the rest is also interesting, I’ll thank you for the video!!!!

I like your videos and am looking forward to more new videos. Do you have a video of how you install video eyes and how they work through the mobile application?

Hey there I have the tuya lock with the keypad but I have a question; when I try to lock by moving the exterior handle upwards, it doesn't lock; plus when I lock from the inside (by moving the interior handle up- which works), I can just open the lock from outside without inputting password or anything... Is this something did wrong?

This is what i need. Letters on the paper manual are too small can't see.

Dean, can you please tell me the price of this castle?
