Good part -
1. I haven't come across a battery back, USB cable roll in the market so that definitely is a novelty when it comes to this!
2. It can hold a battery pack and three cables (charger cables or handsfree)
3. The custom embossing was impressive and chic!
The Not so Good part-
1. The space to put your battery pack doesnt have any thickness so you end up with a very tight space where you need to shove in your battery pack really tight. Scary that the edges of the battery pack may come tearing
2. The belt is longer by around 2 inches and doesnt make it appear to be a roll. I had to send it back to be shortened (shipment borne by black canvas)
3. The custom embossing and delivery took around 7 days and shortening belt and delivery back took another 7 days :(
I am using this product as part of my daily use and corporate travels, this product is an excellent Utility companion. Easy to use, compact, good quality leather, well built and nice formal colors to match my corporate look. Thanks Black Canvas for coming out with such product and in such compact dimension.
