5PCS Technical-Parts, Power-Function-Parts-Set Battery-Box Infrared-Remote-Controller-Receiver M-Motor Compatible with mainbrands

My kids and I are into building intricate setups together and I thought this set of technical parts would elevate the fun. I honestly was surprised at the great quality of the set. It was very easy to use even with the limited directions, and made it fun to be able to add the element of movement to their build. The only drawback is that we play with these a ton, so I had to order some rechargeable batteries to use with it cause we were burning through batteries fast, lol. Definitely worth the money and works well with name brand building blocks. Would recommend!

These work well with name brand block toys and others. I cannot upload the videos of what we use them with due to guidelines, but they work great, they fit fine, and we've had no issues. I would definitely recommend them. Lots of fun for kids and grownups alike.

No issues with these as well, fit was good no real compatibility issues with name brand parts.

Our kids are really loving this addition to their building block sets. It helps bring their creations to life. They love being able to build vehicles that drive and other moving things. As an adult, I really love playing with it as well. I highly recommend this for anyone wanting to bring their building block creations to life.

Was able to make a lego technic RC car, which was exactly what I wanted. The flashing is kinda sharp, and the plastic feels slightly lower quality than lego oem. It works, however.

This is basically identical to the name brand set, but at half the price. Really great for making motorized builds. It is large and bulky, but that's just necessary to hold the batteries. Know what you're getting in advance, and you'll be happy with it like we are. No real complaints.

My grandson, eleven, loved playing with these! There wasn't much of any instructions included but it didn't take him long to figure it out and build something with them. The power bank requires six AA batteries and the remote requires a few as well. Batteries are not included, so don't forget those. I did and had to empty the batteries from my candles because he was so excited to tinker with these. Everything worked well. We had a little trouble at first getting both motors to work with the remote, but a little tinkering and we figured it out. It was not clearly explained. We've never used the name brand power functions so I can't compare to the original but I was impressed with these. They fit the bricks he has without issue. The motors are a bit loud. About as loud as an electric toothbrush. I feel that takes away a bit but my grandson didn't seem to notice. Considering these are a small fraction of the price of the originals, I am thrilled and will be buying more.

Large motors, switches to make your blocks move.These are large so it may look bulky on some buildsController did not come with this set as advertised. The motors are not correct either. I hope customer service will fix this order and update their site.

初期不良かと思い、販売者に連絡したら翻訳した日本語っぽいがちゃんと対応はしてくれそう。今回、コントローラーの方のライトが光っているのにも関わらず、コントローラーが効かない（普通はライトが光っていたら電池に問題はないと思ってしまうが、電池を変えたら動いた。）ので、初期不良と思ってしまった。皆さんコントローラーで動かせないと思ったら、ライトが光っているいないにカ関わらず、まずは電池を変えてみましょう。
