No complaints. Get them for 1/3 the price while you can. Haha ### ⭐⭐⭐⭐⭐ Rotary, NOT RANDOM ORBITAL (Sumake ST-C121) *by L***W on March 27, 2022* I was looking for a low speed 3”:random orbital sander when I saw this listing. Under the heading “about this item” the fourth paragraph down calls it a Mini Random Orbital Sander from Sumake. Without putting compressed air into it I could see that it was rotary, not orbital. Sending it back unused because not orbital, but with over 45 years experience using and owning air tools I can say this is a high quality professional grade tool. The photos of the higher rpm model 120 and the 121 call the speed control switch a reversing switch. If a sander like these were to be reversed, the pad could spin off. Maybe I will try the higher speed model 120 and hope that turning the speed down doesn’t cause excessive vibration like some 6” DA do at low speed. ## Frequently Bought Together - 3 inch Mini Pistol Grip Air Polisher and Sander, Pistol Grip, 2100 RPM, Composite Housing, (Sumake ST-C121) - DEWALT Buffer Polisher, 7-in-9-in, 12 amp, Variable Speed Dial 0-3,500 RPM’s, Corded (DWP849X) - 3M Perfect-It EX Machine Polish, 06094, High Performing, 1 qt (32 fl oz/946 mL) --- ## 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.us/products/128550049-3-inch-mini-pistol-grip-air-polisher-and-sander-pistol](https://www.desertcart.us/products/128550049-3-inch-mini-pistol-grip-air-polisher-and-sander-pistol) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-11-15*
