Review on 🌑 Premium Graywind Roller Shades & Blinds: Explore 100% Blackout Fabric Samples by Sam Calderon

I almost decorated my house with Alexa except for the blinds. So I first ordered two of these smart blinds. They were excellent so I only ordered eight blinds from the seller. I uploaded a video showing Alexa blinds voice control. In short, great smart blinds and great customer service. Below is a list of pros and cons: One important thing about delivery time. It tells you the months before shipping, but it takes 2-3 weeks to arrive! Excellent customer service. Best thing I've seen with Revain in 7 years. I could easily give 10 stars just for their quick replies and helpful email discussions. They will make your order according to your needs. Many thanks to "Tina" and the team! 2. Very good blind material.3. Smart blinds, voice control, battery operated, scheduled operation. It also has a remote control to control individual blinds or all with one click. You can set the schedule in Alexa app after adding all blinds in Geeklink app and hub. You can group the blinds as you like in the Alexa app.5. It runs on batteries, which is a big plus since you don't have wires to power it. I've just been using them for a week. Let's see how long the charge lasts. I drive the blinds twice according to the schedule (open in the morning, close in the evening) .6. The installation is very easy. Only you need to drill two on the blinds (inside the bracket).7. The charging port is outside, so it can be easily connected when needed.8. If many blinds are ordered they will pre-program the remote control so you don't have to do any programming. Just add it to the application. Cons: 1. Nothing at all except the Geeklink application which only has three controls (Open, Close, Stop). Hopefully they'll add a voice prompt like "Open 20%" or. "Close 50%" etc.2. Programming blinds with a remote control can be difficult. You just need to follow the steps.3. Sometimes I saw that one of the blinds in the group did not work as planned. Not sure what the problem was. But you can close it with Remote/App/Voice Command4. The sound of the engine may seem too loud. Really loud. But it won't wake you up :) Overall, I'm very happy with the product and the great customer service (they even offer discounts on many blinds). Let's look at the durability and charging frequency. Updated before commit if there are problems or not.
