取説がついていなかったことだけ残念。 品物はキレイでちゃんと動作しました。

Not happy with this product. Gave to my grandson for his birthday and only worked one day. Very disappointed little boy !!

I purchased this as a birthday gift, and it turned out to be a great choice! It arrived on time, was exactly as described, and felt like a quality item right out of the box. The presentation was nice, which made it feel even more special to give. Most importantly, the recipient absolutely loved it and has been enjoying it ever since—that’s always the best part. It’s one of those gifts that strikes a perfect balance between thoughtful and practical. I’d definitely recommend this if you’re looking for something reliable and well-received for a birthday!

1度2個のうち1つ壊れて、リピートしてますが、リピートしたうちのひとつがまたおかしくなりました。 今度は振動で光るタイプを他のショップでリピートしましたが(合計6個目) どうやら電池入れる蓋の内ゴムが結構ハマり弱くて、うまくハマってくれないのと、 電池との接触が悪く光り辛い製品が多いようです。 光り方自体は結構明るく、綺麗に光ります。このタイプの製品はどれも壊れやすいのはほぼ確なのでそこは注意 だいたい１ヶ月くらい？で片方がおかしくなったりします

For me, It works well. I'll provide a video to show it in action. Must put it closer to the center as it spins faster this way and the designs show up better. It goes through a bunch of different designs overtime. It does not stay on just one design. You'll have to have your own batteries btw. Installation wasn't difficult but may take a few tries to get it just right.
