love the set!
purchased this set for my 10 yr old son for xmas. He's obsessed with it! He enjoyed every step building it. his one and only complaint I hear is... " mom, I don't like how the tires squeak " as he's pushing it along the table. other than that, He's very pleased with the lego.

Missing Pieces
Not even through step 1 and pieces are missing… very frustrating for the cost of this set.

Great Build But......
This is a brilliant building experience, I enjoyed it from beginning to end. The end of the build however is when my experience became disappointing. Having put on the wheels and tyres the front suspension gave way on both sides, the red pins popping out of the supports and the front dropping to rest on the tyres. I have tried reinserting the pins but the same thing hap...

Response from Staples :
It’s never fun when things don’t work the way they should. You might want to try the LEGO Builder app for the 3D version of the instructions to catch smaller details. You'll want to make sure that each part is positioned exactly as shown in the instructions and that everything is pressed together firmly (except the gears, which need a bit of space to turn). If you’d like a hand troubleshooting the build, feel free to reach out at LEGO.build/Service‑BV, we’re happy to help!

Amazing build
I am absolutely in love with this set. It had the perfect mix of challenges and the easier build techniques. It looks amazing and the highlight of the build had to be the transmission honestly lego have some talented and creative people working for them to even make that possible down to the working paddle shifters. Blown away by this set would reccomend to anyone looki...

Not bad, only 22 hours over 2 days to build. It was an impulse buy.

Beautiful set!
I love cars and racing/Formula 1, and found this set on clearance at a local retailer. What a beautiful set. The P1 and the Ferrari SF24, are just gorgeous sets, and great fun to build. The functionality is incredible, and the details really stand out. The only gripe is that it is very expensive at full price.

I got there in the end!!
As a recent convert to Lego as a 65 year old hobbysist i finally decided to tackle one of the largest sets having practiced on smaller Technic sets and some Creator/Icon sets. This is another level in complexity of build. The gearbox alone is a master and quite amazingly connected to a paddle gear changer mounted alongside the steering wheel. I even shocked myself, it w...

Wheels
You see how everyone in the ‘fan moments’ only show the driver side. It’s because the passenger side wheels stick out far too much. Fix that. It’s a sports car not a monster truck

Response from Staples :
Thank you so much for your review! It would be frustrating to have a set that isn't resembling the sports car the way it's meant to! If you would like to rebuild your LEGO® Technic™ McLaren P1™ we'd suggest double checking your build as there may be a piece just a little off from where it should be and make sure that all the pieces are pressed tightly together to make sure the wheels line up. Please reach out at LEGO.build/Service-BV for our brick-helpers get your sports car ready for show!

The Best 1:8 Car So Far...
A thoroughly enjoyable build but suffers from the same problem that I have encountered with all recent builds - They all suffer from an unnecessary proliferation of brightly coloured or contrasting grey parts (Both LBG & Dark Grey). Most of these parts are hidden so why are they even used? One area where they are not is just under the exhaust - Why is that Dark grey are...

Best build yet.
I have built all the super hypercars. The McLaren has been the most enjoyable to build. The smaller bag
sizes is the best yet. Thank you Kasper for a great design!

Fine model, but 6/7 speeds worked
The first gear was a cracking sound once I pushed the car when the wheels roll, 6 of the gears worked perfectly and smoothly on hybrid mode, but the 1st gear makes a creaking sound when I push or pull it. Maybe we recommend this set if it is a beatiful set and also play functions worked well.

Perfectly splendid
I would choose this experience again without hesitation. The building process was thoroughly enjoyable and rewarding. However, I did notice that certain elements—such as the door—lacked the desired level of sturdiness. That said, I truly appreciated every moment of the build. It’s just the minor details and final touches that could use some refinement. Overall, I’m very...
