is the best LED smart dimmer available.- Quality product, and in many rooms the cons aren’t an issue- Controls up to 17 8.5 watt led bulbs- Has unique ability to modify/set the high and/or low end of the dimming range (i.e. set the dim range so a bulb/fixture will dim lower)CONS:- Lutron certifies bulbs for use in the dimmer and many bulbs, including the top rated BR30 GE Reveals, will not work in this dimmer. We like to use the new ‘vintage look’ LED bulbs, and none of mine work properly in this PD-6WCL-WH Caseta dimmer.- The problem must people have with this product is it’s inability to set a default dimming level. When turned on at the switch it goes to max brightness.Many people, like myself, like that when using LEDs with a dimmer, you can buy bulbs brighter than you could for an incandescent, and it only adds 2-5 watts and virtually no heat. This allows you to light a room super bright if needed, but use the dimmer so you can tone it down for everyday use. Here in lies the problem with this dimmer. It starts at max ever time you use the switch. This is terrible for a bathroom in the middle of the night.The last thing is the layout is complicated. Guests won’t know how to use it, and you have to pause and think before you choose a button (especially in the dark). It not like a GE paddle where you can walk by and quickly tap it up or down.If you like the layout, I strongly suggest you check out the Caseta PD-5NE-WH dimmer switch. It uses a neutral wire and functions with way more bulbs (I check compatibility myself - if there’s no flicker, hum, or on/off flash they work). It also has a button for a preset default, but it is a little pricey - no more pricy than spending $54 on a dimmer and switching it out!See my product review on Caseta’s more advanced dimmer (PD-5NE-WH), it resolves almost all of this products issues.

bridge installed without any issues and works flawlessly with its app and Alexa interface. Remotes are a little fiddly to program, but I've seen worse.The big issue is compatibility with fixtures. If you install these switches with dimmable LEDs, the fixtures must be on the list of compatible equipment provided by Lutron. I tried to use fixtures that were not listed as compatible and ran into serious operational issues (flashing, flickering, unpredictable dimming). Suffice to say that anything not on the list is likely to give you headaches, and it is almost certain that the super-inexpensive fixture you found is not certified.

2 switches and 2 remotes.Installing the switches was easy, though I prefer the GE design where the wires are inserted into the switch body, rather than using wire nuts as Lutron has done. The hub was also easy to install, though it looks like it needs to be on the same switch as your WiFi access point.The remotes have a lot of possibilities. I can put switches in new locations, such as on both ends of a hallway, without having to run new wires. And with the wall mount adapter and a new cover plate, it'll look like it's built into the wall!My only complaint is that the switches are rather particular about the bulbs if you're using LEDs. Not all dimmable LED and CFL bulbs are compatible, and non-dimmable bulbs just plain won't work.

After noticing this I actually had to buy some more picos just so I can have this function in some areas of my home where I don't want the lights to go to full brightness each time I turn them back on. This really upset me a bit and had I known this prior to installing them I might have thought twice and looked for another switch instead. The other thing I really don't like about these switches are the way they look. To me they look outdated and need to look more modern and sleek. So many other switched out there now that look insanely good, but just don't offer the same features. If Lutron corrects these two issues its a 5 star product all day.
