Do you have to put your hand in a awkward position to do it?** A: Hi, It's more in the pressure it takes to click the button (switch), Most of my mouses and trackballs have hair pin buttons meaning it doesn't take much pressure or finger muscles to click. This one is pronounced, it takes more pressure which over the period of time this adds up. I would send it back if it wasn't more trouble than it was worth to do so. I got it so I could train my left hand to use it. It sits in the closet now. **Q: How do the buttons feel when clicked? Are they too stiff? Do your thumb gets tired after a long period of use?** A: I was previously using a Logitech Marble Mouse trackball which has a much lighter click action than this unit. The overly heavy button springs are my only complaint with the Kensington. My thumb has gotten stronger in the time I have been using it, but long periods of game play do make it quite sore. In conclusion, I like the Logitech for game play and the Kensington for web browsing. Older users will have more trouble adjusting than younger ones. **Q: Does it have a scroll click (middle click)?** A: With 💩KensingtonWorks 3.1.2 for Windows 10, in Firefox, "Middle Click" does not work for ... - "Right Mouse Button" with "Alt", "Shift", "Ctrl"; - "Left Mouse Button" with "Alt", "Shift"; - Assigning both button being clicked to be recognized as "Middle Click" is a game of chance. "Ctrl" + "Left Mouse Button" works as "Middle Click" without help "KensingtonWorks" software **Q: How long is the cord on the Kensington Orbit Trackball?** A: I did not measure it, but my guess is that it is around four feet long. I got the trackball for health reasons (wrist, carpal tunnel issues). So I had never even taken the plastic twist off the trackball until you asked the question. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 使いやすくて２個目の購入 *by 飽***鍋 on June 16, 2018* 昔からトラックボール色々使ってきましたが（ロジクールとかエレコムとかマイクロソフト）、１年前に購入使いやすくて愛用、先日ノートPC買ったので２個目購入、もしも壊れてしまったらまたコレ買うと思います。製品の寸法 115ｘ140x46 ケーブル1480ｍｍ ### ⭐⭐⭐⭐ Theトラックボール *by ヱ***丸 on May 2, 2020* 低価格有線トラックボール6年使用でスクロールリングの動きが悪くなったため買い替え。低価格ゆえ、所々チープだが不快感を覚える程ではない。SlimBlade Trackballも持っているが、こっちの方がネット閲覧には便利。 ### ⭐⭐⭐ スクロールリングなしのトラックボールに耐えられない *by R***K on September 13, 2018* スクロールリングなしのトラックボールに耐えられないです。とりあえず、2個買いました。 ## Frequently Bought Together - Kensington Orbit Trackball Mouse with Scroll Ring (K72337US), 4 1/2X5 1/2X2" - Kensington Orbit Wireless Trackball Mouse with Touch Scroll Ring (K72352US),Black - Kensington Orbit Trackball Mouse (K64327F), Silver/Black --- ## 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.vn/products/741888877-scroll-ring-included-orbit-trackball](https://www.desertcart.vn/products/741888877-scroll-ring-included-orbit-trackball) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-06-08*
