I don't know if the chain is not durable or for any other reason, but when I first connected the belt to the chain, the size of the hook did not match the hole position in the belt, so the hook was broken. It's not completely unusable, but I don't touch it once I connect it.
Also, this may be my mistake as a user, but I recommend you to consider it.
Thank you so much for the honest review, which will be very useful information to other customers. Sorry to know that you encounter such issue when first connet the chain to the belt, and we will pass this information to the factory to pay attention to this. When we do quality checking, we only check if the items are in good condition but did not connect each part, and we will also pay more attention to this detail in the future. Sorry for the inconvenience caused and thanks for your kind understanding. Have a nice day. :)
