I don't know when the last time you actually checked their website but I just went to their website and tested your claim that the shopping cart doesn't work correctly and it is false.
Their order cart works fine. On both the product page and the shopping cart it give a quantity with a (-) on one side and a (+) on the other. I added a single camera to the cart price at $150.00 was correct, I then increased quantity to 9 updated it, price changed to $1,350; I then changed the quantity back to 1 and updated the cart and the price changed accordingly. It even pops up a green bar above the cart that states "Cart updated".
There is nothing wrong with their order process or the shopping cart.
I am even tempted to buy one just to check it out, especially for the low price of $150.00, the bike mount is especially something I would like to check out.
