Impressed

Got this for my son and he loved it! The buttons feel real. It was pretty impressive, the detail that went into this! Makes you almost feel like you should be able to play a game with it!

I love the fact that it looks exactly like the old school nintendos! My kids think it’s cool and honestly I’m low key jealous I don’t have one for myself 😭

Looks Like The Real Thing

This looks great when finished and was very fun to assemble. I think it took me about an hour and a half. I think the price was a little high, but i don't by lego kits often. Maybe this js standard pricing?

I love the buttons

I love that the buttons feel real. I enjoy that you can change the screen to either a zelda game of a mario game. A dope addition would have been to add a sound like you're turning it on.

Great Price for a Great LEGO Set.

I bought one at the original price which was $10 less than LEGO's price, and 2 more on the after Christmas Clearance which was nearly $20 less than MSRP. Truly an Iconic LEGO set for video game enthusiast.

Masterclass

This is an incredible build. The designer managed a realistic look and feel on the outside, accurate interior during the build, and used ingenious building techniques that were so satisfying.

Very cute

I prefer builds with the most pieces, so this was a little quick for me. All in all this is a really cute build. Only thing that would make it better is a sound card.

Gameboy

This Lego build brought back so many memories of when the Gameboy first came out. I started it the day after it arrived and finished it in 3 evenings. I wanted to enjoy it so I took my time building it. Turned out great!

Amazing and detailed

This set is incredible and highly detailed. The lenticular moving game screens are a great touch. The interactive elements like being able to put the game cartridges in really make the set pop.
