- March 9th, 2020Average rating4out of 5 stars4.0Great start with the app control ...Postie33uk | 45-54I would recommend this to a friend!Purchased for: DaughterBuilt this with my daughter who Is showing a intrest in lego that I’ve built so thought ok get this one and the rally car . The build was ok and no real problems. Only down thing which I found and so did my daughter with both models they just don’t go fast enough for kids .. my daughter loved the app control using the touch screen control . But today’s kids want speed ? So please lego change the gearing so future models go quicker, as my daughter who’s 9 get fed up with it going so slow .. I will look and see if can change the gearing myself for her but most wont and just give up on it..Play ExperienceAverage rating3out of 5 stars3.0Value for MoneyAverage rating4out of 5 stars4.0Build Time: 1 daysBuilding Experience: Intermediate LEGO builderWas this helpful?454X4 X-treme Off-Roader

- October 6th, 2019Average rating2out of 5 stars2.0Great model, overpriced, missing remote42099buyer | 45-54Purchased for: SelfAs a long time Lego fan I wanted to get my hands on the first model with the new Control+ technology. First of all, the model is totally overpriced. $249 is a bad joke. In Europe it's available for about EUR 160 on Amazon, so I waited for a trip to Europe to get it there. The box is small enough to fit into a full size suitcase. EUR 160 or roughly USD 180 is a fair price for this set. Building the set is fun, the axles are very robust and it's fun to put all those parts together. Taking the finished model in operation is easy. Downloading the app tool some time, the app is big! After starting the app, I pressed the green button on the Lego hub and then communication was established seamlessly. First the app did a firmware update. Ok, get used to even firmware update your Legos :( Driving the first meters was smooth. The new motors are so much better than the old ones. I'm looking forward to build many models in the future with these new motors. After a few minutes however using the app got tedious. there is no feedback on the screen, it's difficult to know where you are steering. The app is no replacement for the real remote control. I compared 42099 with it's 10 year old cousin 9398, and 9398 is much more fun to play with! Lego, please get the remote ready! If the model had a remote, I would recommend it to my friends. With the app, it's not recommendable.October 7, 2019Keith, Customer ServiceHi there, thanks for your review! I'm sorry you're not a fan of the LEGO® Technic™ Control+ app. We designed the Control+ system to use an app rather than a physical remote because it allows for functionality that's not possible through traditional remote control. For example, you can enable sound effects, real-time speed and tilt information, challenges & achievements, and one-finger gesture control! If you need help using the app, please get in touch at LEGO.build/Service.Play ExperienceAverage rating1out of 5 stars1.0Level of DifficultyAverage rating2out of 5 stars2.0Value for MoneyAverage rating3out of 5 stars3.0Build Time: 5 hrsBuilding Experience: Advanced LEGO builderWas this helpful?254X4 X-treme Off-Roader
- July 31st, 2020Average rating4out of 5 stars4.0Great CrawlerMrSilverback | 45-54I would recommend this to a friend!Purchased for: SelfA short review for what’s ultimately a short build... however... what a great looking model! In summary not a challenging build but there are some interesting technics involved. What you get here however is a fantastic little machine. Certainly not spritely, but a fantastic little crawler. You won’t regret your purchase. I would highly recommend this build for the experienced and less experienced Lego fan alike as both a great build experience (not hard, but enough to entertain) and a great active model. This is a crawler through and through and a lot of fun is to be had building obstacles to scale. There are a lot of stickers to be applied, I nearly didn’t but don’t regret their application as the model does look great, I do wish however Lego would move to printed parts (as with Lambo) as feel this would match the quality brand that ultimately is Lego. Parents of younger build fans should be mindful of both stickers and need for smart devise to control vehicle. In summary a fun build, a great Technic set which will give hours of fun both in build and play. In my humble opinion a classic of the future. Enjoy.
