Solid, functional switch.
Great switch, easy to install. Works very well and the buttons have a good feel to them. I bought this to control a bathroom fan so it couldn’t be left on accidentally. As an unintended bonus, it’s also a good way to time the length of ones shower.

Newly installed, but it works nicely. Pay attention to the white wire.
I put this on a bathroom exhaust fan and it works perfectly. Note that in order to wire this up when there is no “neutral” wire present, join the ground wire from the switch and the neutral (white) wire from the switch to the ground wire from the house–all three capped together. That is not made clear in the instructions, so I tried to install this by simply capping off the white wire and leaving it unused, but that doesn’t work. The fan will run, but the switch isn’t in the loop. A Leviton tech support person got me straight.Other than a very small click when it switches off, this switch works silently. No tick-tick or annoying unclamping noise then it shuts off.It appears Leviton decided to sell the color change kits generically and not personalized for each of the many time options on these switches, but I can attest to the color change kit being very easy to install and that they look good. The difference is there are no numerical labels on the buttons. Instead, there are markings to indicate the length of “on” time. If you know your switch, the printed numerals are not needed. The kits are on Amazon too:https://www.amazon.com/dp/B0C9WCWVHQ?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1Can't speak to the durability of the switch, but I will update this with any good or bad developments.

My wife absolutely loves these
When I plumb a house I always run a complete hot-water recirculation loop of PEX under each fixture to be used. I then install a recirculation pump near the water heater, and in the past have the outlet serving the pump be controlled by two, three, or even four switches. One major problem. No one ever flipped off the switch after using, and the gas bill actually went up over a non-tankless system.I even put in lighted switches so people would know when the pump was on. They still left them on – must have thought the switch was a cute nightlight. So I contacted the engineers at Leviton and described my needs and asked if they had a solution. They got back to me within two days, and even had a manager do a follow-up to be sure someone had contacted me, and this was their solution.Since my wiring was for using three-way switches I was concerned a timer like this would not work. Easy solution. You simply install two of these and both locations can independently turn on the pump. The time you push has a little green light by the selection, and that shows on the other switch as well. The directions are complete and make wiring easy.Just be aware you will have needed to run either a 12/3 with ground or a 14/3 with ground, or code also allows you to run two 12/2s or two 14/2s. You just have to be certain you have two hot leads (red or black), a neutral (white), and a ground. Don’t fudge and potentially cause a bad situation.Now there is an alternative. You can use one of these and their remote switch, which pairs with this timer, It is less expensive, but the drawback is that it only will turn the pump on and off. The time set is determined by this timer, and if the last use was one hour then pushing the remote switch will turn on the pump for one hour, even if you only wanted 15 minutes. Or if you wanted an hour but the timer last was used for 15 minutes. So it has limitations. That is why I chose to install two of these.For larger projects you can install one of these and then multiple remote switches, serving the purpose of a standard four-way switch setup. But you will have the limitation of all remote switches using the last setting on the timer. I do not believe they make four-way timers, but it never hurts to ask. I sort of doubt it though.Anyway, my wife was the chief culprit of leaving on the pump and she had gotten to hate having instant hot water. After these were installed I got a big hug and was told these are the best thing I’ve done on the house. Strikes me as a bit of an overstatement. So for my farmhouse remodel I have two more of these to use for that recirculation pump. I get the two-hour version because that is about the length of the dishwasher cleaning cycle before it switches to drying mode.Great little devices, and mine have worked perfectly.

Works great, pay attention to the wiring diagram.
Works as advertised; I replaced the deco style fan switch in a bathroom and it fit perfectly and does what it should (runs the fan for the selected time period and then turns it off). Installation is straightforward, but pay attention to the wiring diagram: in my case, there were three wires at the switch: line, load, gnd; there was no neutral (white) wire; this is common. The new timer switch has 4 wires and all 4 must be connected: black->line, other black->load, and you must tie the neutral and gnd together. What many may find easy for installation is to use two 2-wire lever nuts (one each for line and load) and one 3-wire lever nut to tie together the incoming (bare/green) ground wire from the switch box to the white and green wires of the new timer switch.Also, I bought this because it is CSA approved; I would not install anything that is not tested and certified by an NRTL (UL, ETL, CSA, TUV).

Works as it should.
Solid switch, really easy install. Functions as intended, and fits well in the original switch cover plate. The only thing I wish is that there was a full on button, but I guess thatâs my error when purchasing.

Very pleasing, made of plastic
Easy to install, pleasant to use. Functionality for the installer and the user are great. Extremely, intuitively practical. Makes the bathroom seem much classier.Both the buttons that it came with and their custom buttons are cruddy. They feel cheap and wobbly, and you can easily see their internal lattice structure.The upper wall plate bracket is low quality plastic. It is flexible, challenging to true, and was a poor fit to all my screws.It isnât loud, but it is much louder than any of my rockers. I notice it from across the house when it works, and it is loud enough to disturb my sleep from a few feet away.I wish it came in more colors. The lime green light is bright and looks too computerized for my bathroomThe whole thing feels like cost cutting, and the price kind of feels like a ripoff. While I prefer this layout and appreciate that the switch works well, Iâd choose something else if I had a neutral wire.

Timer works great.
The time select is great so that the bathroom fan is not forgotten for hours on end
Gary –
Simple and easy
Wired this up myself. Very simple and love the timer. My kids turn on the bathroom fan and never shut it off. Now I donât have to worry about that.

This is an excellent option for those bathroom exhaust fans that only have 60 mins. This can run partially thought the night and day to eliminate condensation and ultimately mold forming. Best for main bathroom or most used shower bathroom. Reasonable cost as well

Vert good, significantly smaller than earlier versions, so easier to fit. The description may not be clear, this type of timer can be set to a time, or turned off, but never set to ON (without a time-out). That’s what I wanted, but some units can be set to ‘full-time ON’.

Working good, installed this timer switch for baseboard heater.

I am so happy with the installation of these timers. They look great, they work exactly as they should, and I found them fairly easy to install – they took me about 15 minutes each. Leviton is a trusted brand so I appreciate the quality of the build. The green indicator LED is nice and the buttons don’t feel cheap.My household tends to leave the fan on in the bathroom for long periods of time. This obviously wastes electricity but it also directs heated or cooled air out of the house needlessly. We purchased two different timers – one with shorter durations for our two-piece bathroom, and one with longer durations for our bathroom with the shower – and they are both working as expected to help prevent fans from running all day.Installation was very easy and the instructions were nice and clear. They give different wiring options for different wiring scenarios which is very helpful but if you’re uncomfortable doing this yourself, an electrician should be able to wire these pretty quickly. They can be wired with or without a neutral wire which is also nice option for some homes.
