No tax except for NJ or NY I think. Shipping is free.

Yes, I know, there was GE for $20 and $35 with double tap. The real deal here is if you need a 3 or even 4 way - you can use your existing old school switch, no need to by companions.

One caveat with these (and many others) is the minimum load required:
"Compatible with LED, CFL, and incandescent bulbs - minimum 15 Watts on load required"
I tested them and they work with smaller load just fine. Then I spoke to Zooz and they said the internal switching circuit may or may not go bad after months/years if the load is lower. I also spoke with the SM because many other switches and relay from different manufacturers have the same warning, even if they don't have it in the manufacturer's manual. They claim they discover this with their personal experience and it holds true for many of the switches. So if you want to be safe, used it with 2 or more LEDs or a single 100w equivalent.

Remember - if you have 5% review coupon you can use it today too.

Keep this in mind in you're using this with LED bulbs/fixtures that can be very low wattage (3-5 W per bulb).

That is correct. I tested them and they work with any load. Then I spoke with them about this and they say the internal circuit may or may not go downhill if it's used with lower loads. It's more of an insurance on their end.

Regardless, I will put that in the OP so people are aware.

Nice price. I hope there are more z-wave deals coming. I need a new controller. I'm watching Vera to see if they drop the price again on the VeraPlus.

When you post a review on their website, they email you %5 off. Usually same day but since today is holiday I doubt it.

Thanks picked up 4. Can't beat that price for 3 way switch! Heard great things about these so I am excited to try.

Edit: err have to cancel as they aren't dimmers. Ugh

My understanding is/was that the dimmer function can be erratic with the lower load(s)

Has anyone actually set these up in a 3-way configuration? I am trying to figure out how difficult it would be to setup...

I did. Very easy if you have existing 3-way. All you need is a neutral in each box and then you can use one of the spare travelers to move hot to the box before the load/light if you don't have it already.

Does the 2-way configuration require a neutral?

They look very similar to GE switches so I'm assuming the 3 way setup would be the same, not too hard but I would recommend a multimeter or at the very least, a testing light.

On another note, have they improved the feel of these switches or fixed the screws that cause them to not work? The GE's have a much smoother click to them and they match other switches perfectly where the Zooz are too white and stand out when compared to the covers and other switches IMO.

This is not a dimmer.

I have ZEN22 dimmer and tried it with only 5 watts (they ask for 20) and dimmer worked. However, it way fail over time.

I thought the dimmer was great but I can't recommended now. Ramp up/down is to slow, it changes it's minimum brightness level on it's own somehow (at least with my bulbs).

Whenever possible, I used ZEN21 to save money. Where extra functions are needed, I used HomeSeer switches/dimmers for their double and triple tap functions (amazing but 2+ times the price)
