Listed as 【Technical Specification：User Manual [PDF ]】 Review: Excellent office trackball. - Excellent office trackball. - It's easy to use - It has plenty of buttons for customisation and software to remap them - Small enough to not get in the way but still comfortable - Accurate with very little lift-off (better than the huge trackball in this aspect) - Very useful scroll wheel. Trackballs without a scroll wheel are annoying. - Lightweight and easy to carry - Wireless, so no cables to deal with. - Sufficiently sturdy plastics and no sticky rubber. - Good price for a trackball. The only downsides are - The back and forward buttons don't work on a Mac - The polling rate isn't high enough for gaming (you get aliasing problems). Review: Great track ball mouse - Bought this while experimenting with using track ball mice - good place to start but didn't end up being my thing - good quality build ## Features - 《Hand-Shaped Unique Design》The mouse design is based on 6 different muscle and skeletal structures of the hands giving special emphasis to the folding actions of the hands to provide a new level of hand comfort. - 《Optical Tracking Technology》The DEFT wireless trackball is an index-finger operated trackball with unparalleled operating performance. - 《Functional 8 Buttons》It comes with 8 physical buttons on the device and the two extra buttons are the scrollwheel tilting that allow horizontal scroll. The high durability left and right button switches passed the click testing of more than 10 Million clicks. ELECOM Mouse Assistant software can be easy to customize button functions. - 《DPI Cursor》Designed with a high-performance gaming optics system sensor and lens. The DPI button can easily change between 750(LOW) and 1500(HIGH) DPI, making the movements of your cursor faster or slower. The ball is held in place by the ball bearings, but can easily be popped out of the device, by pushing it through the hole in the bottom and it can be easily cleaned. - 《Product Details》System requirements: Windows 7, Windows 8.1, Windows RT8.1, Windows 10 or later (Horizontal scrolling function is not working in Windows RT8.1), macOS 10.10 or later, Size: W3.7"(94.7mm) X L4.9"(124.4mm) X H1.9"(47.9mm), Weight: 4oz(without battery), DPI: 750/1500 count (switchable), Connectivity: Wireless USB2.4GHz ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0171QQ7FM | | Antenna Location | Gaming, Office | | Are Batteries Included? | Yes | | Are Batteries Required | Yes | | Battery Average Life | 6 months | | Best Sellers Rank | 15,054 in Computers & Accessories ( See Top 100 in Computers & Accessories ) 535 in Mice | | Brand | エレコム(ELECOM) | | Brand Name | エレコム(ELECOM) | | Button Quantity | 8 | | Colour | Black / Black ball | | Compatible Devices | Computers with Windows and macOS OS and USB port | | Connectivity technology | USB | | Country of Origin | China | | Customer Reviews | 4.1 out of 5 stars 2,537 Reviews | | Enclosure Material | Plastic | | Global Trade Identification Number | 04953103473713 | | Hand Orientation | Right | | Hardware Platform | Mac, PC | | Included Components | Batteries | | Item Dimensions L x W | 12.4L x 9.5W centimetres | | Item Type Name | Wireless USB2.4GHz | | Item Weight | 113 g | | Manufacturer | ELECOM | | Manufacturer Part Number | M-DT2DRBK | | Model Name | M-DT2DRBK | | Model Number | M-DT2DRBK | | Mouse Maximum Sensitivity | 1500 Dots per Inch | | Movement Detection | Optical | | Movement detection technology | Optical | | Network Connectivity Technology | USB | | Number of Batteries | 1 AAA batteries required.

I work on a PC for 8 hours a day, and was starting to feel the pain ramping up. I could feel the movement of a normal mouse wasn't helping the issue so started reading into alternatives. A lot of trackball mice these days use the thumb for the trackball, which wasn't an option for me and I eventually settled on this one. It took quite a lot of getting used to to be able to use this accurately and efficiently, I have had this mouse for just short of a year now and using it is second nature. At first the ball doesn't really roll smoothly in it's cup, that improves with time. DO NOT use alcohol or any solvent to clean the ball/cup, the oil from your skin actually helps the ball roll smoothly so don't remove this if it can be helped, just wipe any dust away with a cloth. I feel I've had it long enough to confidently comment on it, the quality is brilliant, this thing feels like it'll still be going strong in 10 years easily. There is some Elecom software you can use with this mouse that lets you customise it to the nth degree. I have my 3 custom buttons at the top as cut, copy and paste, my left thumb buttons are forward and back. There are endless options for customising this and the software is great once you get it into English mode as it starts in Japanese. It seems to go through batteries quite quickly (needs changing every month) but I do have to have it on the higher power mode because of the distance from my PC. It only takes 1x AA battery though so it's no hardship. My one gripe and this is only really a personal problem (hence no star reduction) is that I would've preferred a trackball with the scroll wheel around the trackball as it is on some other mice. Having it thumb operated can sometimes cause me some pain, but I'll generally avoid scrolling this way if it's anything over a couple of pages. ## Frequently Bought Together - ELECOM DEFT Trackball Mouse, 2.4GHz Wireless, Finger Control, 8-Button Function with Smooth Tracking, Ergonomic Design, Optical Gaming Sensor, Windows11, macOS (M-DT2DRBK) - ELECOM DEFT PRO Trackball Mouse, Wired, Wireless, Bluetooth 3 Types Connection, Ergonomic Design, 8-Button Function, Red Ball, Windows11, MacOS (M-DPT1MRXBK) - ELECOM HUGE Trackball, 2.4GHz Wireless USB, Index Finger Control, Customizable 8-Button, Large Soft Palm Rest, 52mm Ball, Windows PC Mac (M-HT1DRBK) --- ## 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.mx/products/50740662-elecom-deft-trackball-mouse-index-finger-2-4ghz-wireless](https://www.desertcart.mx/products/50740662-elecom-deft-trackball-mouse-index-finger-2-4ghz-wireless) --- *Product available on Desertcart Mexico* *Store origin: MX* *Last updated: 2026-08-22*
