I'm really impressed!
I bought this kit for my grandson for Christmas. We just built it today. I have to say I am really, really impressed with the quality of the design and the components. Everything went together very easily, and the directions were top notch. It turned on and performed well! This is an excellent kit, with lots of possibilities. The technology available today never ceases to amaze me (I've built about two dozen Arduino projects from scratch over the last few years, but this kit is really good). I haven't even tried the remote control functions with a phone yet. Well done Elegoo!

Works as described, a fun kit that's easy to assemble. No soldering, plug and play. Tools included.
Kit arrived on time, just as described. Worked the first time after assembly.Code was preloaded, app worked flawlessly.The physical assembly was not challenging at all for a 6th grader that can use a phillip's head screwdriver.

Good robot with some flaws
I bought two of these for the purpose of modifying them into differential drive robots with caster wheels. Here is my assessment:1. The robots work out of the box for its designed purpose. 5 stars for that.2. Hardware quality is superb. 5 stars.3. Tutorial/doc is OK. 4 stars.4. Example code quality is not great. 2 stars.Flaws:1. Motor encoders have A/B phases, but phase B is not hooked up to any pin. As a result, you cannot tell the motor’s rotation direction, making position PID control impossible. Remedy: I cut the traces for the IR LEDs and wired phase B signals to these pins. Now position PID works. I should not have to do that though.2. Only one free pin left on the Arduino Nano used. This would be a much more expandable robot if they had used Arduino Mega2560 instead.

Works perfectly! Best in class.
I recently purchased two-wheel self-balancing robots from three vendors. This one is the only one that works correctly including the iOS app for my iPhone.A similar device suffers from balancing issues and another balances perfectly but the iOS app would not connect and the Windows app would not install.

Great learning tool!
I bought this robot during the summer of my graduate school in mechanical engineering last year to practice C++ code. Although it is only a $80 dollar robot that is great for kids with multiple modes that can be controlled with your phone, it is also a very sophisticated product. It uses PID and a Kalman Filter, both concepts that I learned in graduate level mechanical engineering classes. I was also able to use data from the robot for my system ID class and my grad project!The company also has great support and turn around time when you email them with questions related to the code on the robot. I would suggest this product to everyone young and old who have an interest in engineering/robotics!

Somewhat unstable.
A quick assembly with small bolts. Battery pack looks pretty good. The product does stand up nicely but becomes unstable quite easily. The tire to motor connection works but wobbles just a bit and this may be a major cause of the instability.

Superb Quality Hardware ... *AND* actual customer support!
I've recently put together a couple different mobile robot kits and the Tumbller is easily the highest quality. The parts are clean and assembly is straightforward using nothing more than the included paper manual and screwdriver. In fact, it took longer to charge the battery than it did to assemble the Tumbller. When I finally turned it on, it stood upright as promised.Some of the screws and parts are quite small so manual dexterity is required and you should work carefully over a table or bench. Elegoo thoughtfully provides a small number of extras in case of loss during assembly.The one complaint I have is the difficulty of finding the software. The Elegoo website is largely devoted to their 3D printers with only the vaguest links to their robot cars. It required many start-over attempts plus some imaginative Google queries before I was finally able to track down what I *hope* is the github package, and I have no assurance that the sources thus obtained are what's actually running in the Arduino Nano.Getting the source code is important to me because I want to understand the self-balancing algorithm and I also hope to devise some sort of radio control other than the smartphone app provided. One possibility is replacing the Nano with a Raspberry Pi Pico W or some other microcontroller that is WiFi capable. This is certainly going to be $90 worth of fun!Update: I finally obtained the Arduino source code for the Tumbller but was unable to get it to work due to a certain section of code which caused the Nano to reset. As a last resort I sent an inquiry to Elegoo support. Rather to my surprise, I got a reply indicating the technical solution. Support like this speaks well of Elegoo as a vendor.
