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!
