Folks, this is super fun to install - and this is coming from a guy who is not at all good at DIY skills. I cannot comment whether it's easy or hard to install because that will depend on your OCD levels lol - i.e. these come in puzzles and you'll have to assemble figuring out the small complete map with hints. The tricky part, for example, is that Asia and Europe come in separate parts, which mean you'll have to connect Finland's border with Russia's. Now, my OCD levels are high so I spent ages getting the border control right - meaning, there is no gap between Finland and Russia. Other than the adjoining Russia and Finland, it was fun connecting Egypt with Israel, again because of the tiny piece of land they're connected with and you wouldn't want to break that connection. All in all, it is super fun to assemble.
I cannot be happier with the product.
