But some of the power generation fuel is used to maintain the lifestyle of a set of privileged state employees.According to these CEB employees, long lines of CEB vehicles used by engineers have become a common sight at the Kelanitissa power station. These vehicles often carry barrels and other containers to take additional diesel supplies. These employees complain that although diesel is issued from the Kelanitissa storage under the guise of supplying the essential needs of maintenance and breakdown vehicles, only a small fraction of that fuel is allocated to CEB’s field vehicles.The engineers in the meantime have an almost unrestricted supply of diesel for their official and private travel (sometimes including daily travel of their spouses), despite the people agonizing in long fuel queues all over the country.

Longer warranties are nice but not required.In fact, the CEB has been advising its customers that the time taken to attend to breakdown complaints will be longer because its maintenance vehicles cannot get sufficient fuel.ĬEB engineers are allowed to commute between their homes and workplaces, subject to a maximum of 20 km each way plus additional private travel allowance ranging from 600-900 kilometers per month at board expense. Warranty: Most problems with trackballs arise from quality-control quirks and surface in the first year (if not in the first week) of use, so we expect to see at least a one-year warranty.Older trackballs with aging software, fewer buttons, and wired connections are available for $20 to $40.

Price: The most recent models with modern software and better build quality tend to cost $50 to $100.Each connection type provides a strong signal that doesn’t cut out over short distances. Connection: Some wireless options support a 2.4 GHz USB wireless receiver (a dongle), Bluetooth, or both.Some trackballs use AA batteries, while others have a rechargeable battery. Battery life: If you opt for a wireless trackball, you can expect anywhere from six months to 24 months of battery life.Great software also lets you change the pointer speed, acceleration, and scrolling speed. Software: If your trackball mouse has four or more buttons, you’ll likely want to customize how they work with manufacturer software.Comfort: A trackball should be comfortable for any size hand and not require wrist extension or deviation to operate.
Buttons: We look for the same amount of buttons as we do on wireless mice-a trackball should have at least left- and right-click buttons, but we prefer models with at least two additional buttons for back and forward.The bigger the trackball, the less rotation you need to employ to move the cursor across the screen. A low-quality ball can ruin the experience of using a trackball. Ball: A trackball should rotate smoothly, without gritty-feeling friction.(For more information, see Should you switch to a trackball? below.)Īlthough trackballs can help some people with some symptoms of repetitive stress injury, they can’t help everyone-we recommend consulting a doctor first if you’re considering a trackball for that reason. We also have a budget pick-the Kensington Orbit Trackball Mouse with Scroll Ring-if you don’t mind sacrificing build quality and a couple of features for a more affordable trackball.įinger-operated trackballs with center-mounted balls work for both right- and left-handed people and encourage better wrist posture, while thumb-operated trackballs are more similar to traditional mice and therefore easier to get the hang of. After spending more than 120 hours testing eight trackballs during weeks of work, we found that the best trackballs are the finger-operated Kensington Expert Mouse Wireless Trackball and the thumb-operated Logitech Ergo M575. A trackball isn’t as accurate as a good-quality mouse, but it can be more precise than a trackpad for anyone looking to eliminate repetitive motion from mousing around too much.
