9LUCKY TECH New Technic Series Parts - 280 Pieces Beams Axles Connectors Bricks Sets- Compatible with All Major Brands

I don’t recommend this product not only because it’s a set of fake LEGO parts, but because the grears won’t work properly. The clutch gears won’t engage due to bad flank design and the regular ones won’t work because of their unmatching teeth shape. That is why I returned the order. Hope these words help.

I knew going in that these were not made by Lego, however they seem to be good quality, and I got every piece in the picture. My only complaint is that there are 448 pieces, not 450. Even in the picture there are only 448. The item description should match what is being purchased exactly.

Works with original LEGO Technic pieces but is much cheaper. My son built cars, a coin pusher and a small belt sander with these. Zero complaints after two months.

Updated review:The seller agree to refund this purchase due to my unable to use it. Really appreciated. Great customer service. Recommended. Thanks.Original review:I guess it's my bad: these are not Lego parts so we can't use it for building a robot for FLL purpose. If seller see this and let me return/exchange for Lego technic parts, that will be great.

Well worth the price (cheaper than lego brand) and seem to be same quality. Its nice to get a decent amount of parts without paying an arm and leg. My boys love em and we've got all kinds of contraptions going now.

This has heightened my little engineers building ideas. For the price it’s a must have

Work just as good as lego. Great company and great customer service! This fit well and are interchangeable with regular lego.

Was exactly as described and works with lego pieces, Use it for practice builds, cheap and worth it.
