As an electrical engineer I like having the freedom this product offers by having no pre-defined locations for ICs. I can put anything I want anywhere on the board and that allows me to have much greater efficiency in the use of the space. I was surprised that it was so hard to find this option and am delighted that RobotShop had this. I have several projects going on and chose the lowest cost shipping since I knew I wasn't in a rush. Wow, be careful about that - the product took nearly a month to arrive, which I suspect is unusual and maybe a factor of winter weather. Nevertheless, in the future if I need something in predictable time I will go with their flat rate UPS shipping which is very reasonable. Shopping around and considering the prices that RobotShop is offering compared to some competitors, I can actually offset some shipping cost pretty quickly. All in all a good experience.
