Analog Jeans

What do you think about Analog jeans? I got my first pair of Analog jeans yesterday. It had a button fly. When I tried them on for the first time, one of the buttons fell off. Later, as I tried to see if the other buttons were like that, another one popped off. Luckily, the top (main) button seems to be very solid. I don't know why they made the other buttons that way. Fortunately, they're still very wearable, and you wouldn't be able to tell anything happened. I love these jeans. Of course you can't judge any entire brand based on just one item, which is why I'm wondering about other people's opinions.
