So I will say the actual quality of the product is pretty fantastic! A couple of pieces were difficult to fit together, but no big deal. The directions are probably my only proper issue with the entire purchase. At times, it took me a while to figure out where some of the pieces were supposed to go. There are a couple of points, within the build, where pieces fit in a way that make it almost impossible to back-track if you made some sort of prior mistake. One last gripe, if you mess up with the stickers, the way they peel off causes the sticker to get this weird design, so just be careful of that if you want it to be perfect. Again, I am extremely happy with the final product and you can not beat the price. 100% worth it in my eyes. It is genuinely Lego Technic for half the price.I’ve bought a couple Lego Technic knockoffs and this one is by far the best. It’s a beautiful mock representation of the Ferrari F1 car, incredibly solid when assembled, and a spectacular value. Considering Lego only offers McLaren (meh) this was a great option for fans of the red car. I will say the instructions are a bit lacking and at times a little challenging to follow, nowhere near as clear as a proper Lego experience, but I like the challenge it added.Wasnt holding my breath buying this before there were reviews, but was pleasantly surprised. Instructions not quite as good as a Lego set, some ambiguity but easy enough to follow or work out. So many spare parts that I was paranoid I missed something as you know what to expect in a Lego kit. A lot of the spares are for installing a motor in the last section of the manual. To the other reviewer with the strange part that is their version of the tool to remove, split pieces. Would recommend as it's a bargain and looks greatI was very skeptical when I purchased these. They seemed to good to be true and very inexpensive for the quality. I must admit I have been pleasantly surprised with these. I saw this exact model for around 100 dollars on other websites and ended up finding it on Ali epresss for around 45. I ordered from Amazon for the free shipping was not let down. At around 50 bucks this set is a great deal and I had a blast building them.Overall had a great time building this but only concern is not sure why I was left with so many left over parts and there is one part I have no clue where it goes or how it's used for this build I left a photo of the part in question. If anyone knows where it goes please let me know thank youAt 1/3 or1/4 the price these kits are exactly the same as Lego. I’ll get a couple more soon.Want to torture yourself? Enjoy undecipherable drawings? Like watching parts fall off 3 pages after you've installed them? Then go ahead, buy it.I'm done.Looks great and was fun to build. It was missing 2 pieces that luckily weren't detrimental to the build. (steering column spacer and exhaust circle piece. But for the price I am happy
