Review: Technics lego - The Technics pieces arrived on time and am happy with the product
Review: Exceptional Technic Parts and Outstanding Support for Building an RC Car - I recently purchased the "ASTEM 413PCS Plus Technic-Parts..." from desertcart CA, and I couldn't be happier with my purchase. I used these parts along with a Power Function set from another seller to build an RC Car, and the results were fantastic! I got those sets for my kids, ages 4 to 7, as a birthday gift, and of course, I had to supervise them while playing with the sets. Initially, I struggled working with the sets. However, the seller, ASTEM, went above and beyond to help me with the build. They provided excellent support and guidance, ensuring I had all the necessary parts to complete the project. Even though the power function units were from another seller, ASTEM kindly provided me with a detailed PDF containing step-by-step instructions and a block plan to assemble the car using an IR receiver, remote control, 1 m-motor, servo motor, and other technic parts. The quality of the ASTEM parts is top-notch, and they fit perfectly with the other components. The instructions were clear and easy to follow, making the assembly process smooth and enjoyable. I highly recommend ASTEM for their excellent customer service, high-quality products, and dedication to ensuring a positive experience for their customers. If you're looking for reliable and well-made technic parts, look no further than ASTEM. They truly care about their customers and their projects!

### ⭐⭐⭐⭐⭐ This is a great value product!
*by L***R on 13 February 2024*

I was concerned after reading a few reviews about missing pieces but thought it looked like a great kit for the money. I am actually quite impressed with the quality as it rivals the brand name product in every way. The parts are indistinguishable and top notch. I thought I was missing a piece close to the end of a build section, found I had an extra piece that was very similar (half height vs full ) and realized I had used the full height piece at a step earlier in the build instead of a half height piece. Before I discovered it was me being careless and not Mould King I reached out and had a reply in under a day. I confessed in a reply that I had found the part but one of my motors was binding and wouldn’t power the assembly. I advised the manufacturer and again got a prompt reply and a promise to send out a replacement. Very good costumer service. The build was super satisfying and quite enjoyably challenging. I plan on buying more from Mould King instead of the other recognized brand due to the high quality and excellent value for cost.
