### 1/5 — lousy support

*2020-12-17, version 1.7.1*

does not work with new iterations of phone OS.

### 3/5 — Zetlight WIFI Switch A100 Not Working With iOS14

*2020-10-03, version 1.7.1*

Zetlight WIFI Switch Do Not Work With iOS14

### 4/5 — I’ve used several units for several years

*2020-06-10, version 1.7.1*

I’ve owned several units for several years and they work good. You have to make sure it has a strong connection to the internet otherwise it will cut out and come back on when it looses the signal. So what it does is it goes bright as the light does at 100% it’s normal working capacity without a100 and then then it will dim to the setting you have set

Having a 5,000 tank in my house and being able to simulate sunrise and sunset, cloud cover, lightning ect ect has been, a good show off for people coming over and it’s been healthy for the koi fish I own. 

8/10 for the unit 

Great price too

### 2/5 — App needs update

*2018-11-26*

Could some please update the app. There seems to be a issue with the time on the app itself.

### 4/5 — Works really nicely, would be cool to have presets

*2017-09-13*

Took a while to get going but got there in the end. This app is very good and runs smoothly. It would be really cool if there were some presets to select from. Overall very impressed with this smart piece of software.

### 3/5 — General Review

*2017-06-02*

Hi Zetlight.
I love your lights and I do think they are wonderful peaces of tech but your app is absolutely shocking to work with... Please can you guys upgrade your interface and make it more modernized. It's not user friendly and toke some time to set up. It would be much appreciated for all of your faithful costomers🙏🏼

### 1/5 — sounds promising, but no instructions

*2015-12-10, version 1.0*

got me exciting for few mins, then when i try out; no connection. scan does not found my light or my light controller. There is no instructions how to connect either (or info on what it need to connect).

too bad, this is could be good app and i was planning to promote it in my fb group. 

oh and in iphone 6+, it show white screen. 

i'll give 5 stars if dev listen and update on above comment.
