I'm pretty sure most mouse aren't BIFL, they wear down when you click so it<s just gonna crap at some point.

I have a MX Master 1. The battery started to die (wouldn't last for more than a day or two). So I poked around online and found some instructions on how to replace it. $5 in parts from ali express and my mouse now has a battery that's over twice as large as the original battery. Now one charge lasts for months.

It’s a giant PIA.

I adore my MX Anywhere 2S!

Got shout out to the 3dconnexion mouse for cad. Only one available with a proper middle button. Five years on mine so far and love it to bits.

Now add the mx keys keyboard. The ultimate work setup.

I have the MX Master 3s (only for about a month or so now) and several other Logitech products, their wireless is always excellent and have only had to plug to charge once so far (it comes with a usb wire of course that you can use if you prefer wired)

I've have the origional MX Master, a couple 2S's, and a 3S (going to order another likely today)...
Function wise, there really isn't any difference between all three versions that I've found, and all of mine still work/charge fine. My reason for upgrading was that my origional MX master started to miss some clicks after years of use/abuse, my 2S's are on my desk and in my bag in use at work daily, and I recently (4 months?) got a 3S from a vendor.
At work I've set users up with probably 20-30 over the years, I've never heard of a battery issue with them and have only replaced one due to a broken charge port.
From the "1" to 2S there was nearly no physical change, a slight color difference, but they nearly doubled the battery life and upgraded the sensor which makes its tracking on any and every surface much better.
From the 2S to 3S the biggest change that took a few days to get used to was how frickin silent it is. My wife nearly killed me a few times clicking away while watching TV with the 2S, the 3S ratcheting scroll and clicks are nearly silent. my biggest gripe would be that they re-arranged the thumb area so back/forward are now in front/behind each other instead of up and down, and they moved the horizontal scroll up a bit to where you almost need to feel for it/intentionally reposition your hand.
That said, I'm kinda in love with the 3S now, and if they could do "something" to fix the issue I have with my pinky getting a divot from how I hold it (every one of my mice has a wear spot about 1.5 inches in from the back right corner from my pinky rubbing) it'd be perfect lol.

Huh. I didn't know you could reload rimfire.

I have an MX Master 3. The rubbery material they use on the exterior surface wears really quickly. There's no way I'd consider it BIFL.

Should add: I own mechanical computer keyboards that I would consider BIFL, because they are made of far more durable materials and can be serviced by a competent user even if they switches wear out (which is unlikely). Keycaps can be easily replaced by anyone as they wear out. I just don't see the same emphasis on long-lasting quality in ANY pointing device you can buy today.

I get that, but (correct me if I'm wrong) doesn't BIFL stand for 'buy it for life'? If there isn't a reasonable expectation that the item should last decades at a bare minimum, what are we all talking about here?

Context: I own an MX Master 3. The plastic/rubber coating has HEAVY wear after only a couple of years. There is no way I would ever consider this thing BIFL under any circumstances. But I can think of a whole bunch of ways its design could be improved to focus on greater longevity.

I understand that most products are so far away from BIFL these days that the term has become a bit of a chimera, but sometimes there are some real head-scratchers on this sub.

Non-removable rechargeable battery, capacitors, and electron migration are all things make most electronics hardly BIFL.

There is a small cottage industry of modifying these and old S&W revolvers to shoot 32 center fire so they can be used with the Colt 32 rounds that still get made in collector batches.

But it seems a shame to pay a $500 to ruin an antique just to have a gun that shoots worse than a modern $400 22.

They still exist today as a e-commerce seller. And was founded 100 years ago. Don’t know I plastic will make it 100 years…

It’s the Stevens Favorite action which is a different type of falling block.

That's pretty awesome. Does it have a sharps action?

I looked and don’t see a wired version. Anyone have problems with the battery or wireless?

I see the newer versions 2, 3, 3S are out now. Any opinion if one is better functioning than the other?

Function is my focus as the number of hours in use makes its cost per day tiny.

By strict definition only solid metal items with no gears or connections are BIFL. But talking about only hammers , axes, and anvils gets old quick.

A focus on quality that lasts and performs better than average, or is economically superior via an amalgamation of quality and price,…

Nice! I’ll remortgage the house and go plinking.

I still wouldn’t consider it buy it for life but definitely its a great and durable product. But better that you posted something that you use heavily unlike others who post electronics that they never use and say it BIFL. My mx mouse is still going strong and i hope it get to the 8 year mark

Surely by definition this is not BIFL?

It’s the best built mouse on the planet. Have had two sinse 2007 and only replaced became the new version was Bluetooth and paired easier with multiple devices

Can’t really vouch for the longevity of my x2 MX master 2 but both are still solid after years of use… fully expecting the same as OP, either the micro usb breaks or the internal battery gives up (I’m sure this can probably be an easy fix). But I can vouch for all the other points made, they are an excellent piece of kit 👍🏼
