It just to early for me to get an honest opinion. I have not use it for a for a long time so let’s see . Thanks

I've been waiting for a switch like this! The switch itself has an excellent build quality, and the buttons all have a nice tactile, solid feel when pressing them.Others have touched on the other great features of this switch from a "regular" user perspective. For the more technically inclined, this switch has an ESP8266 wifi control chip that CAN be flashed with Tasmota or whatever other alternative firmware you like. It does come with the new firmware that Tuya-convert hasn't yet solved (as of July 2020), so it will require you to get out your soldering iron or flashing jig. The chip is a standard TYWE3S and the pins are all easily accessible. The connection between the high and low-voltage boards is also done in a very slick way- no ribbon cables here. To flash the firmware, you'll also need to put a temporary jumper between ground and the pad labeled "NRESET" on the board right next to the TYWE3S to keep the secondary TuyaMCU in a reboot loop while you flash the main controller chip. Digiblur has an excellent writeup with pictures on his blog, search for "Digiblur tasmota fan controller" to find it.Following those instructions, I now have a fan / light controller hooked up to Home Assistant and working great. Excellent job, Treatlife!

I bought this as a higher end circular polarizer to reduce glare and it does everything I bought it for, just be careful about over tightening it, I actually cut my hand trying to take it off once

I have ordered 5 of these now and love them. Excellent for showing who the trespassers are!!
