Started building soon afterwards but soon came to a halt because of a missing parts, luckily because there are so many parts I could rob from another bag. Unfortunately this continued through out the build and eventually I had to order 4 missing parts from Lego and had to wait until they arrived because I couldn&rsquo;t rob any further forward. I got there in the end but it certainly ruined my build enjoyment but not fully, having said that the overall quality and experience of the final product is brilliant and god only knows how someone has designed this &ldquo;Congratulations &ldquo;</span> <div class="bvseo-pubdate">Date published: 2024-01-18</div> <meta itemprop="datePublished" content="2024-01-18" /> </div> <div class="bvseo-review" itemprop="review" itemscope itemtype="https://schema.org/Review" data-reviewid="1152841060"> <span itemprop="reviewRating" itemscope itemtype="https://schema.org/Rating"> Rated <span itemprop="ratingValue">5</span> out of <span itemprop="bestRating">5</span> </span> by <span itemprop="author" itemtype="https://schema.org/Person" itemscope><span itemprop="name">LegoGuy5</span></span> from <span itemprop="name">Awesome Set</span> <span itemprop="description">I received this set for Christmas of 2023 and I was over joyed. When I got home from visiting family I started building the set it all went well from start to finish. I did the test and everything worked perfectly like it should, so I continued the build. However when I finished I was proud of the way it looked but when I went to calibrate my piece of ART, on the first attempt it did nothing. :( After this happened I took a look inside the grill and found I had missed a gear. I fixed that and calibrated again this time it lifted the blade but did not tilt it as it should have. I am still trying to find a fix for that, but even after the issues I would definitely recommend this set to those who get pleasure out of building it and displaying it. I will post another comment once I find a solution to the issue tilting the blade during calibration. :)</span> <div class="bvseo-pubdate">Date published: 2023-12-31</div> <meta itemprop="datePublished" content="2023-12-31" /> </div> <div class="bvseo-review" itemprop="review" itemscope itemtype="https://schema.org/Review" data-reviewid="1150626178"> <span itemprop="reviewRating" itemscope itemtype="https://schema.org/Rating"> Rated <span itemprop="ratingValue">4</span> out of <span itemprop="bestRating">5</span> </span> by <span itemprop="author" itemtype="https://schema.org/Person" itemscope><span itemprop="name">MechanicalCryptor034</span></span> from <span itemprop="name">Flawed</span> <span itemprop="description">Let me start by saying that this is a mammoth and rewarding build with a BIG however... In my experience with this build (and I have several Control+ models) is that if you don't pay precise attention to the illustrated extended dimensions of the mechanical rams in the instructions when building it will not calibrate successfully. Furthermore, if you repeat calibration for whatever reason (as I did) if these rams are not close to those specified lengths at the start it will not complete the recalibration and may cause mucho gear clicking in the process. Mine works fine now based upon my earlier advice but I will never calibrate again! Without a doubt this is the poorest Control+ app calibration I have encountered.</span> <div class="bvseo-pubdate">Date published: 2023-11-29</div> <meta itemprop="datePublished" content="2023-11-29" /> </div> <div class="bvseo-review" itemprop="review" itemscope itemtype="https://schema.org/Review" data-reviewid="1150588301"> <span itemprop="reviewRating" itemscope itemtype="https://schema.org/Rating"> Rated <span itemprop="ratingValue">5</span> out of <span itemprop="bestRating">5</span> </span> by <span itemprop="author" itemtype="https://schema.org/Person" itemscope><span itemprop="name">AuntPleasantClouse100</span></span> from <span itemprop="name">I can&rsquo;t wait to build it</span> <span itemprop="description">I just bought this set and even though I&rsquo;m not allowed to build it until Christmas I cant stop thinking about it and reading other reviews I can&rsquo;t wait to experience the challenge of testing and building it.</span> <div class="bvseo-pubdate">Date published: 2023-11-28</div> <meta itemprop="datePublished" content="2023-11-28" /> </div> <div class="bvseo-review" itemprop="review" itemscope itemtype="https://schema.org/Review" data-reviewid="1145461980"> <span itemprop="reviewRating" itemscope itemtype="https://schema.org/Rating"> Rated <span itemprop="ratingValue">4</span> out of <span itemprop="bestRating">5</span> </span> by <span itemprop="author" itemtype="https://schema.org/Person" itemscope><span itemprop="name">Darkdesire</span></span> from <span itemprop="name">Tr&egrave;s belle construction mais</span> <span itemprop="description">Excellente exp&eacute;rience de construction, dommage que Lego ne pense pas forcemment aux personnes n'ayant pas de smartphone (comme moi), du coup la jouabilit&eacute; est tr&egrave;s limit&eacute;e sauf &agrave; r&eacute;aliser des modifications cons&eacute;quentes d&egrave;s le d&eacute;but (ce que j'ai fait).

Full credit must go to the designer as it is beyond me how someone can design such a complex bit of kit.

The automatic test procedure half way through helps to reassure you that so far all is OK. The bluetooth software is magnificent but remember to turn the sound on your phone on as you miss a lot as I did to start with.
