Logitech M510 Wireless Mouse

Late December 2023 Review: After removing the batteries and pushing aside the flex-strip inside, I found a couple of screws that when removed allowed me to carefully pry the upper and lower portions of the clamshell apart. Now --- I pride myself on being clean but after looking inside, one might surmise me to be closer to a pig. A good deal of debris was everywhere despite my frequent outside cleanings and fine-brush dustings in cracks. Took it into the garage and blasted the circuitboard and switch/wheel components with CRC Contact cleaner & went back at it with one of my fine brushes. From what I can tell after reassembly is that not only is it clean as a whistle but it seems to be much better behaved. Time will tell of course but it has earned itself a spot in the hardware drawer as a travelling backup. Will test a bit more but it doesn't seem to be too terribly worse for wear, even after six years. Having said that, I did purchase the HP430 wireless mouse. The clamshell is a tad larger than the M510 and it uses only one battery instead of two. Clicking functionality is great. Wheel scrolling is a tad more coarse than the M510 but livable with both. I would rate both mice about the same for performance with the 430 using only one battery, thus being a little lighter to use. For now the M510 is relegated to "backup" which is just fine. Both pretty decent mice in my view.*********************************************My M510 was purchased in July, 2018. This review is Mid-December, 2023. So, for those thinking the mouse might just be worn out, you could be right.********************************************* That said, the mouse has performed quite adequately in a home office environment with a retired user. Use has been general (not gaming) but steady. I do a lot of reading and a fair amount of Excel-work. It has not been subjected to light-duty. Rather, a medium-duty level of work. Also, of note, I chose to NOT install the Logitec software available for this mouse. I am formerly IT before retirement and our tendency is to always try NOT to install software whenever possible. Windows generally does a pretty fair job of serving attached hardware with the library of various drivers at its disposal. Over the last four months, this mouse has given me a lot to growl about. Left-click latency is noticeable. Frequently, mouse-clicks won't register at all. I will have to double-click and that becomes a problem wheen you have your mouse settings on "hover and single-click". In fields with multiple words (e.g., URL address box), a single-click into the space gets the entire string of words highlighted, ready for deletion. Not good. Worse, when working in folders, I've single-clicked on sub-folders and had them disappear altogether. Thank GOD for 'Ctrl + Z' to pull the deleted folder from the Recycle Bin. Perhaps I've made my point. Also of note, the plastic cap on the USB dongle periodically falls off thus challenging my penchant for all repairs "glue", which doesn't ring appropriate with electronic devices. The unit takes two AA batteries and I use rechargeables (GOOD ONES). For all you IT guys aout there ... Fujitsus are better than Enelopes in my view. Do your research and you may come to agree. At any rate, I get about three months from a set with the mouse switched off every evening. All-in-all, this $20 mouse is just that. Perhaps I've worn it out. I don't know. Suffice to say, it's a 4-star mouse when new and after six years, it's a 2-star mouse. This time around, I'm going to purchase a HP 430 wireless mouse. At about twice the price, it's still affordable and my history with HP is both extensive and positive. Over the last few years, I deployed (personally) several thousand HP computers, monitors and other peripherals. The failure or trouble-rate with HP was extraordinarily low as I also managed (as a key IT employee of a Fortune 500 company) corporate deployments and hardware warranty issues. Even as I've retired, I still choose HP whenever possible.
