SCS Direct Light Up Building Bricks with On/Off and Dim Ability- Multicolor Lights of 40 Pieces - Tight Fit with All Major Brands

Speedy delivery, great pricing, item as described and all light up blocks work!

Work well. A little difficult to handle

I doubt they will last long, but my grandsons who are crazy about Legos did think these were very unique and added a lot to their creations.

some didn't light up and stay lit up. there were only 8 pegs to turn them on out of 40 lights. they do not dim. they are difficult to turn on and off for a child.

Overall very cool. There was one dud in the pack. They are a little hard to turn on but totally fine. I do wish there was an even amount of each. But score because we got more of the party flashing ones. I was hesitant to spend the $30 but is worth it imo. Very cool.
