Great helmet, horrible Amazon delivery.
This helmet is comfortable, lightweight, visually appealing, and at a great price. I can’t comment of the durability just yet, but thanks to the delivery from Amazon, it’s already aged like a fine wine.My package arrived late, in a taped up and misshaped resemblance of a cardboard box, and appears to have been delivered by Ace Ventura himself after being kicked down the street and closed in the door once or seventeen times.Every other helmet I’ve owned wants you to replace it after a big impact of some kind. By the looks of box this thing came in and how the packaging inside that box looks, it should probably head straight back for the warehouse it came from for warranty replacement. Unfortunately, I need to use this tomorrow (thankfully it arrived late but ‘on time’ still) and don’t have the time to return it and get a replacement that isn’t scraped and scarred like I’ve been climbing with Alex Honnold for the last few years.This is not an issue with Black Diamond and the quality of their product, this thing is bomber and looks really sweet. Amazon in the other hand, if you need tonight see more than a roll of packing tape to fix a box that has been destroyed and it’s contents falling out, cut your losses and send a new item to your customer. I would have been embarrassed to deliver this package if I was the driver. Maybe that’s why he delivered it to the wrong house, thankfully I have good neighbors and this thing is ready to protect my head from whatever is falling from above.
Thank you for your feedback
