Actually, it was this one: http://www.amazon.com/gp/product/B008WEP5HE

But they look pretty much the same. Probably bought by the boxload from the same manufacturer and just sold under different retailer/brand names.

WRT to modification, yeah, a lot of these toys are often not too great, and need little tweaks here and there. Especially the "hard" items ... it's like the people designing and making them never use or beta test them. It's why people are willing to pay a big premium for stuff from Mr S or other known retailers, because they are savvy and know and test every, if not just design it in-house.
