(COLOR OF BASE MAY VARY.)★DURABLE, STRONG, SURVIVE MUCH LONGER: We REDESIGNED its key parts. Compare to other gyroscopes, ours can survive much longer: thus you don't have to comfort a crying/disappointed child just after one day or even one hour. Video attached which contains some experiments show this great advantage of our product clearly. Meaning of those experiments is: if it can survive 15 feet drop, it can survive 5 feet (In most cases when drop the height will be around 4-5 feet) easily. ★PAY MORE TO GET MUCH BETTER GAMING EXPERIENCE: We do believe that our DG-5PRO can provide much better gaming experience since several important improvements were made to make it more reasonably structured, much sturdier, with bigger and thicker frame (can be held tightly when pulling the thread, thus get higher initial speed), heavier and to make its rotor spins longer by using ball bearings. Is this worth the 20 or even 40 more bucks you paid? You decide it. ★GREAT TIME KILLER: It can magically stand on almost any places: fingertip, tip of a pencil or a thread. Is truly addictive. Our product is much more robust than any other traditional gyroscopes on the market, will survive when drop from high places to hard ground (which always happens). It's great for adults too: whenever you want to start or end a conversation, this one is a very good choice. ★WHY CHOOSE US?!: This product is a well-designed and crafted mechanical toy, a fantastic gift for people you love. Many people bought our gyroscopes as gift to families, teachers, friends and seldom will it fail to cheer them up! DjuiinoStar has gained very good reputation on Amazon since 2018. We hope you will like it and we do hope you will think it worth the money invested. And we stand behind it to guarantee that. ★Initial speed of the rotor is around 8000 rpm. Personally I like to hold it in hand to feel its power when I was bored. Can't say it's the best gyroscope available, but when take the price into consideration, this is the best one. ★★★★★IMPORTANT NOTE: SLIGHT VIBRATION IS NORMAL ESPECIALLY WHEN IT JUST START BECAUSE THE INITIAL SPEED IS TOO HIGH. PLEASE AWARE OF THIS BEFORE PLACING ORDER.★★★★★ Gyroscope for adults.
