It is high. After all, if it is used at the site it becomes heavy equipment so heavily and it becomes heavy tool. It deforms when things hit. When the fastener deforms around, when you have a handle for carrying it, the fastener is disengaged and every time you use the resin hammer to correct the deformation. Besides the handle in the middle, we think that it was suitable for us that the products with hands for holding hands are used to some extent hard at the work site on both sides of the tool box. I think that it is a product which is light at all and does not have any problem for those who use it. Well I think that the product is weak against this type of tool box box shock. It may be good to love each time you repair it every time you use it.
