HCNT Levitation technology Principle
Why it can float ?
Magnetic levitation system is widely used in the areas such as high-speed motion and precision engineering industry. In reality, a stable levitation with a 80mm air gap in maximum has been achieved, and the floating ferromagnetic object can carry a 2kgs load in maximum also has been achieved. We have already applied these in commerce, and the technology is also helpful to develop new kinds of levitation system for industries. This magnetic levitation technology is a control method using a ring magnet for the stable levitation of a cylindrical ferromagnetic object. The levitation has a strong stability with anti-disturbance abilities, and weight can be placed on the floating magnet. The magnetic field created by the ring magnet provides stabilities in 3 degrees of freedom of the floating magnet, and a feedback control in the horizontal plane is introduced to the control system. The stable magnetic levitation refers that the floating object is static or is with a controllable rotation motion along one axis. The antigravity force for the stable levitation is provided by the base under the floating object. According to analytical calculation and experiments, the magnetic fields created by axially magnetized permanent-magnet rings have special properties. Along the symmetric axis, the direction of the magnetic field varies at two particular points. This interesting property provides stabilities of the suspending magnet.
The setup of the levitation device is shown in the drawing. An axially magnetized permanent-magnet ring whose north pole is on its upper surface is placed on the base of the setup. Three hall sensors are used for detecting the instantaneous coordinates of the floating magnet at three axes. The horizontal position of the floating magnet is controlled by two groups of coils. The north pole of the floating magnet is also on the upper surface, which is inconsistent with the common sense that unlike poles attract each other, not repelling each other to provide antigravity force for the floating magnet, which is the key point for this technology.

Very Good
Style: M705
I still haven't had to change the batteries since I bought this mouse.
I use it every day, mainly for gaming. It works great, no lag, It's quick and responsive.
Its the best mouse I have ever owned.

Beware of the Top Button!!😁
Style: M705
A smooth but weighted feel on a mouse pad. I have mice that move with a much lighter touch, but this is great for the computer I use with my main TV screen. Beware of the top damnable button, the one just before the scroll wheel. It turns off the clicky graduations you wheel as you roll the scroll wheel with your fingertip. When used it unleashes a whirling dervish of a gremlin, your screen will continue to scroll after you want it to stop. Sometimes it will start on its own! Incantations, voodoo, chick bones, curses and magic wands have no effect. Yelling seems to make it worse. There is no other cure other than to push the top button from Hades again. Clicks from the two main buttons are easily audible but not obnoxious. The side buttons for screen forward & back work very well also. This is my second one of these, the first stopped moving smoothly on a pad, no amount of polishing seemed to help so I retired it.

Important Info for Connecting Replacement Mouse
Style: M705
I purchased the MK705 mouse to replace the same model that had simply worn out after over 13 years of faithful service. The MK700/710 Logitech keyboard is still going strong, albeit with a few worn keys.
I did however run into an issue when installing the new mouse. At first I left the old unifying receiver that came with the old mouse plugged into a usb port. I installed the batteries in the new mouse, turned it on, and found that it would not work. I figured it needed the new unifying receiver, so I turned off the keyboard and mouse and plugged the new receiver into the same USB port. The new mouse then worked but the keyboard would not. I couldn't figure out what was wrong, so I phoned Logitech support. The gentleman I spoke with walked me through the connection process, which was done on their website "logiwebconnect.com". Should you run into the same issue, the process is simple. You probably won't need any help from tech support, but if you do, they were easy to get in touch with.

Still the champ
Style: M705
Love it!!! Got this originally when it first came out. The people who talk about the scroll wheel are not very smart. It has a button to switch from hyper to regular scrolling.
I do use a mouse pad. So it moves fine. Feels very comfortable in your hand. Obviously this is not for gaming. Great mouse for your home office computer.

Dependable, Reliable

As advertised. Logitech, best mouse for your hard-earned cheddar!
It’s not that the (years) old Logitech mouse failed in any operational way, it just got that gummy, sticky surface texture that’s impossible to remove. While shopping for a replacement I noticed an off-brand mouse/keyboard combo and thought, “hey, 2 for 1”…mistake. All was well for about three weeks, long enough that when the gremlins arrived I didn’t immediately associate the new hardware. For the purposes of this discussion, gentle reader, know that I run legacy (what I affectionately refer to as, “Lazarus”) builds. Rigs that started life running Windows Vista/7, died, and that now, resurrected, run 10 and 11, and all that that implies. So, when a mouse started stuttering, of course I thought it was a gremlin in the machine, right? I spent more days than I am comfortable sharing with you pouring over processes and background apps, and registry trims…before Accam’s Razor suggested I eliminate the mouse as a variable. Changing the battery was ineffective, but when I swapped in the ooold Logitech…Yahtzee/Bingo/Booyah…smooth and precise…butter! All I needed was a new Logitech mouse.
So, if you’re here you likely are having mouse issues of your own, or you just need one that works…this is it!
