Terrible customer service, would not recommend!I purchased a SwitchBot Curtain 3 after measuring the U rail I wanted to use it with and found it was just larger than the minimum stated compatible size.The unit comes with a number of different size rollers, and the smallest rollers indeed fit perfectly in the U rail.When activating the robot it made awful scraping sounds and scratched a lot of paint off the inside of the rail. When I removed the unit it was covered in specs of paint and metal.I found the issue was the metal pin on the smallest roller extends beyond the plastic roller and on one side is not finished and is rough/sharp. On the larger rollers the pin does not extend past the plastic. There is some play and so the roller will move in the rail and can touch the side, and in my case the rough metal end catches and scratches the inside of the rail, causing damage to the rail.I sent photos and a video explaining all of this to SwitchBot, thinking they might have a solution (send out a different roller), or at least acknowledge the problem in some way.After several days, I got a reply back stating simply that the high street retailer I purchased the unit from "is not one of our accredited merchants".They've just completely disowned the problem!If you want to support decent companies with good customer service the avoid buying anything from SwitchBot.You will get much better customer service buying something for a fraction of the price directly from AliExpress.
