My NSD powerball lasted four and a half years. With the same amount of use, my Acelete lasted only a month and a half. **Q: noise level ? can I use this at a silent environment like office ?** A: Yes. Our surgeons use them in their offices while on the phone. It makes very little noise. Sort of a brushing sound. **Q: does it have led light ?** A: No, all NSD Spinners with ergonomic/rubber band in black are not equipped with LED lights. However, the Speedometer on the top goes with self-powered back LED light when you spin and reach 3,000 RPM. **Q: What is the difference between the nsd power and nsd titan? the price is as twice as big for titan** A: Their Material and Size are different. PB-688 series Spinner are made of military-grade plastic while PB-888 Titan series are made of zinc rotor and Aluminum Alloy shell. PB-688 is a tennis ball sized Spinner while PB-888 is as big as a softball. ## Frequently Bought Together - NSD Power AutoStart Spinner Gyro Wrist Forearm Grip Strengthener with Auto Start Feature - Hand Grip Strengthener, Finger Exerciser, Grip Strength Trainer (6 PCS),New Material,Forearm Grip Workout, Finger Stretcher, Relieve Wrist Pain, Carpal Tunnel, Trigger Finger, Mallet Finger and More. - NSD Power Essential Spinner Gyro Hand Grip Strengthener Wrist Forearm Exerciser --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.sa/products/1558795-pb-688ac-black](https://www.desertcart.com.sa/products/1558795-pb-688ac-black) --- *Product available on Desertcart Saudi Arabia* *Store origin: SA* *Last updated: 2026-07-14*
