I have couple of these blinds for almost 2 months now. It was very easy to install these. I ordered a 15 channel remote which was setup already to control these blinds and worked right out of the box.
Measurement wise, these came as ordered with expected gap after rolling down. As you can see in video, it leaves room for light to enter. If you want to block light completely, I will advise ordering light blockers they offer with the product. In hindsight, I probably could have used little more height when it rolls all the way down to avoid light coming out from bottom. Something I will keep in mind while ordering next ones. Material for shades is really good and blocks the light completely as expected.
Rolling is pretty smooth and quite enough to not be bothered in night. It can be partially rolled down using either remote or app. App on android (Shademate) keeps crashing on my phone but Kincmo hub I ordered with my 2 blinds worked nicely to integrate support into Alexa. I can control it either through Alexa app or voice control easily.
Lastly, customer service is really good. After going through multiple motorized blinds options, I settle down on Kincmo because of the reviewers mentioning how great customer service is. And it was as advertised.
They contacted my to confirm if I wanted Matter over thread or Kincmo hub and offered to replaced my original order with Kincmo hub instead as it will be cheaper option as I plan to buy more. Their response time is quick and detailed. You can pretty much get all your questions answered through emails.
I started with 2 and might replace rest of them as I go.
