Tedco Gyroscope Silver

Though expensive for a steel ring, its worth it. Kids would enjoy the gyro...

Quite good but what they dont tell you is that adding oil to the pivots is compulsory, not optional. Oiling makes a massive difference in performance. Without oiling my gyroscope would screech and run for 10-15 seconds max, with oil it runs for 60-70 seconds with a strong pull (with proper technique). The Gyro is a bit crudely finished and even the welded joints are not plated over but it does the job. The yellow paint on the flywheel rim peeled off only after a few days of use. Had this been made in China it would not have cost over Rs 100-150 but as this is an American product we have to pay though our nose.

I like the product very much it rotate for quite a while and fun. Excellent product quality wise. I wish it to be little bigger.

Bad Built quality and does not function properly too much resistance, makes noise

Not a very good quality. The paint was not in proper condition. It was looking like a used product.

I it was shaking for sometime and after it was ok

Disjointed corroded frame and very low quality built. It’s extremely overpriced considering the quality. Otherwise, it’s a nice scientific toy to have.

Metal frame . Right size .Rotates well . Everything is just fine.

the item looks cheap , but it's in perfect blance

Broke after just three weeks. It may look like the old school gyroscopes of Gen X childhoods, but it's certainly not as sturdy.

子供のおもちゃにしては 扱いにくい

Bought for my fiancé for Valentine’s Day. Works perfect and is a good size. It’s self explanatory on how to use but comes with instructions. The price is good and it spins perfectly and for a long time. It’s not loud like some others I have seen.

ジャイロ効果を調べていて、簡単な計算結果から予想される事象が起きるか実験するために買いました。 安いので精度はあまり期待できないですが動きを観察するのには十分でした。 台座の上で40秒くらい周ります。慎重に重心を調整すれば60秒くらいまで伸びます。 振動はそれなりにありますが台座から飛び出すほどの振動ではありません。 写真には映っていませんが台座と紐も入っています。CEマークも確認できます。 精度の高いジャイロスコープを想像して買うと後悔すると思いますが、 ジャイロ効果を確認したいのであれば十分でしょう。 この形状のジャイロスコープを世界で初めて市販したのはチャンドラー社のようですが、 チャンドラー社を買収して今でも製造を続けているのがTEDCO社のようです。 そのためかオリジナルのChandler Gyroscopeに似ています（細部は違います）。 商品写真に赤丸で外枠が切れている箇所が示されていますが、 製造時に回転体を入れるために必要な切り欠きだと思います。 外枠を少し引っ張れば回転体を外して外に出せます。
