So, I just received the Sienna Slate from BS and my first impressions are great.
First time buying a case from them, so I'll do a little comparison with my beloved Andar Aspen.
Pros:
• Grip is better than Andar's.
• The feeling in hand is soooooo good. As everyone knows, Andar is a little bit slippery.
• Buttons are better. With the Andar you have to press a little bit more.
• I really missed the open bottom through all those years. All of my cases were closed, so that was something nice. It's like I bought a new device.
Cons:
• I can find only one and that's the smell of the leather. With the Andar was so intense, here not so great.
• The color it's not the same with the photos on their site.
• Εven though it isn't their fault, our customs here in Greece charged me 27€.
