I work at home. 8-10-12 hrs a day. 7 days a week. Last time I changed the batteries was more than a year ago. And a couple of years before that.
""I tried to correct this problem for several years now but now I know, sigh. Anyone else ever had this problem?"" You can get a corded mouse for 10 bux. No muss, no fuss. Look for it, and be done with your worries,
Yes sir. I have learned to have a wired internet connection a long time ago when I use to play xbox 360 online racing games and my car was just lagging.
Work at home is irrelevant; work with your mouse is all that counts. Most people spent more time with their keyboard then with their mouse. Logitech says: "UP TO 36 months." So maximum, in optimal conditions 36 months. "Battery life may vary based on use and computing conditions." If they would be sure about these 36 months they would not have to add this warning.
If you're worrying about the lag of wired mouse vs wireless, than you're looking at the wrong place. For sure, a wireless mouse will lag, but those microseconds will not make any difference in your trading. If you have a problem with you mouse, just change it. Wireless or wired is just a personal preference. A like others said, always keep a backups. A backup mouse, a backup keyboard, a backup computer, a backup router, a UPS, etc.
IMHO, every trader today (to not say a scalper), using extensively the mouse in his trading, should absolutely try all the new computer gaming weaponry. Regarding the mouse itself, a Razer Deathadder v2, not even a top of the line, has a way higher and customizable precision (even more if you add a paired mousemat), faster and realiable optical switch, and a tailored cord with extra flexibility just to avoid any troubles of the kind you are speaking of.
In Windows Control Panel you can access Mouse functions. Reverse the primary and secondary buttons so that your RMB now replaces your LMB. If the double clicking has stopped then you have a worn out switch underneath your LBM. Newer generation mouses have an optical rather than a mechanical switch that solves this problem. The mechanical switch is a thinner than a hair copper leaf that flexes when you push down. The end of the leaf moves up and down between two contacts just like any electric switch or relay. Over time metal fatigue alters the bend of the leaf switch and you get double clicks. It's a mechanical switch problem and not a wired/wireless problem. Used a Razer Naga Trinity for years that recently developed this issue and replaced it with a Naga X. Mechanical switch to an optical switch.
What is strange at my mouse is that it has no infra red light. I went into a dark room to see if there is any light, but no light at all. The lens looks however identical to an infrared lens. Don't understand how this works. But it works very good and very accurate. It is called "TruWave Technology".
