Nice power strip
It seems these days that I have way more devices than I have plugs. So, I’ve had to start using power strips.This is a very nice power strip. The Smart aspect of it is great. What I like the most is the spacing between plugs. Most power strips have a couple of outlets rendered useless if something with a large plug is plugged in. It actually will cover the outlets on each side of it. That shouldn’t happen with this one thanks to the generous spacing.I also love that it has USB plugs for charging devices. It makes it so easy to charge everything while using the strip to power other things.This is a very nice, well made cord and strip. The flat plug (where it plugs into the wall) makes it easy to plug into tight spaces. It really does make a huge difference when the plug doesn’t stick very far out of the wall.Overall, a really nice power strip. I’m happy with it and recommend.

Awesome smart power strip
This is my first smart power strip, and I have to say, it’s awesome. I didn’t think the smart feature would be as useful as it is, but it has come in very handy. I’m using it to control a bank of string lights on my porch, but I can imagine many other cool uses for it. The power strip was easy to set up with the free Smart Life app, though be aware that it only works when your phone is on the same wifi network, so it can’t be controlled while you’re away. This is fine though, as the app does give you the ability to set schedules, even for each individual outlet. That’s one of the coolest features. I expected that the whole strip would be on or off, but each outlet is controllable. It’s really great.

Bug –
It does work
Overall not to bad. I would say instructions are a bit light with no like qr code for the app. The name of the app in instructions was different than app name in store. So took a bit of thinkin to find the right one.Once I got the app everything else seemed pretty straight forward and worked. I have several single Kasa plugs that work. But had an area where a strip plug would work much better and less stuff plugged in.Went with this one cause it was cheaper than the other ones I had gotten. Would have liked to stay in one app, but where I wanted this a separate app actually made more sense.So far no connection issues, timers have worked. So far so good. Granted it has only been 4 days. I will update with more over time, be it good or bad.

Not user friendly
It was low key of frustrating trying to set it up. There is no QR code and the directions say use smart home app. There are more then one smart home app on the playstore. Then when it shows the picture of the product on the app after trying to pair it, it looks nothing like the resemblance and only shows 6 plugs. Then when I tried to connect it with Alexa it was another maze. I much rather work products like Kasa. We might get another plug that easier to use then this.

Good
I may be doing something wrong ? But some of them wouldnât work so not sure if itâs the adapter. Charges devices okay. Love that when you plug in itâs flat for easy use.

Lightweight good for travel
I used this while traveling through the holidays. Thought it didnât work, but I found a tiny power button on the front and then ALL the outlets powered up. Otherwise, I only got the first 2 outlets plus the USB slots functioning. So ya, definitely hit that tiny button in addition to the bigger main switch at the end to get the entire strip running. Took me a couple days just to figure this out, so I havenât hooked up the app to try wireless charging yet. So far so good though. Itâs been great for charging up my laptop, phone, tablet and camera.

Solving power source problems in my office
I have a problematic situation in my office where the best outlet for plugging in several appliances is next to a chest of drawers that limits the space so much that I cannot use ordinary plugs. The flat plug on this power strip allows me to plug it in easy enough and will accomodate all my appliances and has the bonus feature of allowing me to plug USB and c charging devices in without AC converters. I haven’t needed to use the timing app for anything yet, but it may come in handy sometime. I like it.

Works without the app
I love that this works with or without the app. At first I could only get 2 of the outlets to work then realized the blue light above the other 6 outlets need to be lit up to work. I love that the plug is flat so it sits pretty flush with the wall. It also has 2 USB and 2 USB C ports, so you can potentially power 12 things at once. Perfect for Christmas decoration, office use, or just someone who has a lot of electronics.
