" ...  Excellent dimmer switch. ... The best feature is that they can be used with "dumb" 3-way switches, unlike most z-wave switches, which require companion switches. ... Not an issue for me, as I want the dimming function.  ...  "

" ...  The light level is remembered for the next time you turn it on so if you were set to 20% when you turned it off, turning it on will set it to 20% again.  ...  "

comment
" ...  So when you attempt to screw it in, you have a good chance to strip the threads.  ...  "
comment
" ...  The issue with the faceplate screws is related to the ground connection. ... Also, the location of the ground screw is directly behind the top faceplate screw, hence the need for a very short screw there. ... The positioning of the ground screw makes the device not fit in certain electrical boxes. ... The fiberglass boxes, in particular, are difficult because the ground screw hits the box material surrounding the mounting screw hole.  ...  "
comment
" ...  I installed the free replacement and I could hear internal arcing when the bottom plate screw was installed, which is very dangerous and very distinguishable sound. ... Even IF it wasn't hazardous, the ground screw protruded far enough down that the top plate screw wouldn't seat. ... The leads did not want to stay tight. ... The other issue is the the screw hole that holds the faceplate was over drilled or wallered out so the threading was nonexistent.  ...  "
comment
" ...  The wires can sometimes insert behind the terminal screws and will not secure after tightening.  ...  "
comment
" ...  Overall, I disliked the large size (fit) of the unit in a single gang box, I disliked the operational feel of the switch lever (no tactile feedback), I disliked the little slider immediately beneath the switch lever to "deactivate" it (which really isn't described or even shown in an illustration in the USER MANUAL) .  ...  "

comment

" ...  Zooz on the other hand, allows us to rewire all points in a switch circuit, to make the mutli-point control work by keeping our existing dumb switches and only changing one of them with the Zooz smart switch.  ...  "
