Delivery： Ordered on 18 Nov 2025, received goods on 03 Dec 2025. Which is about 2 weeks. Quality： Bought 220 units in total from Okystar. Considerably higher quality than average products purchased individually on the market. I have previously bought a few sets to test the products from other companies so I have a fair comparison. The chassis is thicker but also can see stress markings stemming from drilled holes. This has been observed to be consistent with other sets, not just one set. That said, I've also tested out various parts of the product including wires, screws, Arduino board, Sensor shield and L298N. I'm happy that the robot is fully capable of running and is compatible with online code editor. Service： On this order, I've made requests to cater to parts and components in the exact quantity, including soldering of wires to the motors using different connectors. Lynn and Okystar's staff fulfilled my requests very well and matched most of the parts successfully.

Joystick as described. Good product, will buy again
