Unzipping the zipper is difficult. While it functions, it's likely unsuitable for carrying heavy items. The straps could be improved; they attach with a single stitch and might tear if the bag is overloaded.

This is the second time I've purchased this handlebar bag. It's a very good one, capable of holding a 750ml water bottle and has a pocket for keys or a phone. It stays securely in place because of the velcro straps. It doesn't move around much, even on rough, stony paths. It's perfect for long rides, especially in the summer.

The work is well done. The quality is very good.

The shipping was incredibly fast and I fully recommend this product.
