Very cool

I was amazed with this build, the time spent to make this all come together has to be insane. I had a ton of fun building this, it wasn’t the longest or hardest build but it will have a long life on display for all to see. I recommend it if want to relive a little of the 90s.

Nostalgic

[This review was collected as part of a promotion.] Very cute and nostalgic!! We saving it for Christmas for our son but it looks to be fairly easy to assemble but just challenging enough to where it’ll take some time. Lego never fails with the durability and quality of their pieces

You'll be surprised by the nostalgia

I never owned an original Gameboy, but the Internet assures me this is nearly the exact same dimensions of the real thing. The attention to detail is fantastic: both the volume and contrast dials rotate, you can press all the buttons, you can swap games with a very satisfying click (and they don't fall out!), and the power switch feels like it should be booting up the game in your hands! The lenticular screens are a great addition, and the stands make it a great display.

Nostalgic and fun display piece

What a fun piece! So nostalgic. The details and creative ways to bring the piece to life are amazing. I was most excited about the rubber pieces being used to make it feel like you’re really pushing the buttons. The fuzziness to the screen inserts, just like the OG Gameboy, is so cool. I love how this piece can be displayed. Definitely a must have for your Nintendo fans.

Gameboy

I really enjoyed the build. Espeically for the fact this only has two easy stickers to put on the set. I enjoy that it mimics one of the gameboys from my time growing up as a kid. The best part I enjoy is the realistic buttons on the front and the fact you can remove the game part from the back. The only part I wish was that this set was cheaper as I don't think sets that mimic real life items should be priced near their counterpart.

Loved this build

I couldn’t help but have a smile on my face as I watched how the build came along from when the Nintendo GameBoy title was added to each part. I love the interaction of the buttons and the games. I put this together with both my son and daughter. This will be such a fun piece for my office and a great talking point. So many fun memories with this game system and to see the attention to detail and 1 to 1 scale was fun!

Awesome Nostalgic Kit

[This review was collected as part of a promotion.] Wow! A piece of nostalgia meets lego love! So much fun to have two things I love meet up into one hobby. I love that I can display this on a shelf when I'm done and admire my work. As always, the lego set has easy to follow instructions and the pieces are durable.

Great build, great to display

[This review was collected as part of a promotion.] I really liked the finished product. It is very cool to have on display. It says 18+ on the box but kids can definitely build this. It was easy to follow the directions and easy to put together. This piece is a great addition to the Lego brand.

No Tetris

Excellent and fairly easy to build with great features similar to an original Gameboy. Tetris, however, was the game that was included with the original package and should have been one of the games included. In the meantime, I'll be pursuing a sticker to make one for my set.

Great lego for teenagers

[This review was collected as part of a promotion.] My teenaged absolutely loves this lego. He spent about an hour to build it with lots of concentration. He was really happy to build and play with it. It looks amazing and he loves to use it as a decor for his gaming desk. Such a cool product for teenagers.
