Two aluminum maker arrived dented, then there were two bolts unusable by a production error. And that size does not at any hardware store! The grid has been set as defective. All in all, with rework it takes at least 60 minutes if you're already technically reasonably sent. Guide was ok, but could be improved.
EDIT: After consultation with the seller, the defective parts will be forwarded immediately, quick response of the seller and very friendly settlement. Therefore, correction of the vote.
