Suggestion: how long will you consider changing the wrench? The life span of the brand wrench is not particularly big. You can choose the right service and the right price. (good service refers to the purchase, return, convenient channels, the price can be compared to their own)
1., if only occasionally use one, but choose what brand is no big problem;2. but if you need to often repair brand wrenches, common hand tools such as brand: Taiwan Bao, STANLEY, Sata etc..
