I was at my whits end with not being able to hit ding and always thought it was my timing being off, and not the mouse. I couldn't have been more wrong all this time. It turns out a better mouse makes all the difference in hitting dinged shots.
I just purchased the Logitech M310 wireless mouse for $25. My dinged shots has increased at least 30%. I'm now dinging more than 50% of my shots.
This is a quality full size mouse and has just the basic functions. Left/right click, and the scroll wheel. Its very responsive and took some getting used to.
There's no driver, so nothing to download. Just plug-in the tiny USB plug, restart the computer, and start playing.
One of the cool features it has is a sleep mode, making the single AA battery last up to 12 months.
This new mouse may very well help me add those extra couple of birdies I used to miss all the time.
