The first item I received had a numbering problem and was returned→Manufacturer inspected→ and replaced. Replacement also defective. I told them that I wanted them to send me a product that had been checked by Webike when I contacted them about the initial defect, but the product was sent directly from the manufacturer, whether it was because of the GW holiday or the system. When I checked the product, I found that I could set the number, but the Dial was hard to operate because it wanted to move around with its neighbor, just like the original product. The fact that this kind of product is not Smooth in many ways makes it troublesome for the breaker." I dug through the Review and didn't find anything similar, so I'd like to think that good products are easy to handle, but that's not the case with the product at hand, which is very disappointing. I'm sorry to hear that. As for the 2 stars for durability, I dare not post a picture, but it is because I was concerned about the material of the axis of the connecting part and the way it is fixed. Even if the price is a little low, it is not acceptable if the weak points are easy to see from the outside and difficult to handle.
