flats happen, but they're very rare. you're actually confirming my
point.

it's also why automakers switched to the space-saver spares. there's no
need to carry the weight and bulk of a full size tire when it's rarely,
if ever, needed.

when is the last time you had a flat?

That something
doesn't happen often doesn't negate that it does happen. Now you're
backpeddling.

i never said it *never* happened. i said it's not normally a problem,
and it isn't.

You really think the massive majority of users that do
not encounter Bluetooth problems are posting here about how well their
product performs?

people don't normally post when things work.
they post about problems, looking for a solution.





the reality is that some bluetooth mice weigh less than wired mice.

And the reality is that most Bluetooth mice -- OF SAME SIZE - weigh far
more than wired mice.

no they don't weigh 'far more'.

it's very clear you've never used a wireless mouse of any sort, nor do
you understand the specs *you* quoted.

the two logitech mice in the example *you* gave below have a difference
of 17 grams.

a usa quarter weighs 5.67 grams. three of them is 17.01 grams.

a 17 gram difference is hardly 'far more'. it's close enough that
unless you compared the two side by side, you likely wouldn't even
notice a difference.

a typical wired mouse is ~100 grams.

here's a wireless mouse that weighs just 32 grams, which weighs less
than most wired mice.

Claims to last 21 days but limits that claim to only 3 hours of use per
day. Someone using that mouse all day long at work will have to
recharge it in about 6 days. Guess that's not bad if you like having to
keep plugging in your wireless mouse to keep recharging it, a nuisance
not incurred with wired mice. Oh, and no on/off switch, either, on this
itty-bitty device. A search on "pequeno ems071 mouse manual" didn't
turn up any online manual to see if the batter(y|ies) are replaceable;
i.e., if the wireless mouse is serviceable and to know if the product
weight spec includes an internal non-changeable battery or the weight
spec did not include the weight of replaceable batteries.

you said wireless mice were heavier.

i said not necessarily.

some are and some aren't.

the one above is *not* heavier.

you were wrong.

yes, it's tiny, and with that brings compromises, but you were only
focused on weight, not run time or anything else. no goalpost moving
allowed.


this one doesn't list its weight, but it can't be very much:

3.2 ounces (90 grams), or 2.8 times heavier.

90 grams matches that of the logitech *wired* mouse below that *you*
cited.

so, not heavier than a wired mouse. it's the *same*.

you were wrong again.


Logitech M557 Bluetooth mouse
https://www.logitech.com/en-us/produ...se-m557?crid=7
107 grams


Logitech M100 wired USB mouse
https://www.logitech.com/en-us/product/mouse-m100
90 grams

as mentioned above, a whopping 17 gram difference.

here's a bluetooth mouse that's 66 grams w/o batteries:
https://www.razer.com/gaming-mice/razer-atheris

aa lithium batteries weigh 15g each:
http://data.energizer.com/pdfs/l91.pdf

the mouse + two aa batteries is 96 grams, or just 6 grams heavier than
the logitech wired mouse you cited.

6 grams isn't anything anyone will notice unless they put each mouse on
a scale.

it definitely does not weigh 'far more'.

three strikes and you're out.

it also uses bluetooth 4 and can get 350 hours run time, but if battery
life is more important, the mouse below boasts two *years* on a single
aa battery, plus it weighs just 91 grams:

To be complete, the USB transceiver dongle accounts for part of the
product weight spec for the Bluetooth mouse.

there is no need for a bluetooth dongle since bluetooth is built into
most laptops and many desktops.

however, if the dongle weight is included, then the mouse weighs less
than the specs claim.
