No issues with seller, no issues with product.Product designed well. With no flaws.Great pack for the cash.

Let's start with the motors. They work, but only flat. The rest of the pieces fit, but the fit tolerances are bad. Yes, they snap together, but some require a lot more force than Lego, and good luck getting them apart! Others are loose enough connection you cannot trust them for structural integrity.

I purchased these Technic building parts as a gift for my son, who's passionate about LEGO building. I was pleased with the diverse selection of parts included in the set, which catered well to his creative ideas.The assortment of longer parts, pull backs, and tires stood out as particularly useful and versatile. Despite fitting snugly, they integrated seamlessly with LEGO brand pieces, allowing for smooth construction without any compatibility issues.This set made for a fantastic mini gift, especially since my son had been eager to expand his collection and bring his unique designs to life. It provided him with ample resources to fuel his imagination and continue exploring new building concepts.Overall, I'm satisfied with the quality and variety of these Technic building parts. They're ideal for enthusiasts looking to enhance their LEGO creations with additional components that are both functional and inspiring. Highly recommended for any young builder's toolkit!

These are good technic like parts. Compatible with Lego brand and there is a nice variety of parts here. You can build all sorts of stuff with this, or use it to increase your current part array. The parts are slightly tighter than name brand, but you'll only notice if you are really familiar with working with brand name Lego Technic parts.
