Going from a G602 Wireless Mouse to a Wired G502 Hero Mouse. Will I find the cord annoying?

Hard to know if you will find it annoying, using a wired mouse i dont even notice the cord unless im moving it to a new location.

I've had the g502 for a good while now. I absolutely love it, hasn't malfunctioned on me and the weight is perfect (with all weights in it) :3

You will regret from moving wireless to wired :)
I have Logitech G900, which is wireless/wired chargeable. It's annoying to play games while wired, I'm using wired only while browsing or watching netflix. I can use it around 25-30 hours then need to switch to wired, didn't measure it but it charges quickly.

Also there is nothing wrong with wireless health-wise and performance-wise

I am using G402 (pretty close to 502) for a while, and it is totally ok for me.

What annoys me the most is batteries. I HATE BATTERIES.

I was using wireless mouse for years (Logitect M345, M600 and MX Master) but when I've got my ROG Sica I didn't noticed any problems and I'm absolutelly happy with it.
BTW, I'm still using my MX Master at office and Sica at home every day so I'm switching from one to another every day, sometimes even multiple times - no discomfort because of that =).

Personally I have a G203 that replaced my old MX518, and use them with a cord bungee. I prefer no batteries and the very slight tug you get from a cord (it reminds my hand where the middle of my mouse pad is)

However, that little pull you can get from a cord is not for everyone, and I imagine that if you are used to wireless then you could regret going back to wired until you get used to it again

EDIT: this prompted me to have a cheeky check, and it turns out a new version of the MX518 was recently released. Looks like I'll be getting that when my G203 finally packs in!

now its double clicks every single time i press it.

Replace the button, not a mouse.

Trust me there is that too, even made a thread here about it myself, on a lot of mice.

And most logitech keyboards will give you dead rgb's in the end (but that's pretty much with any brand).

The more fancy (cheap) junk they put in to, the more prone something fails in the end, with any applicance, like a washing machine.

I see the merits of wireless mice if you're using a laptop that you constantly carry around, but I've personally never been inconvenienced by the cord on a desktop PC. I don't even notice it's there, but I'd certainly notice if my mouse suddenly died because it ran out of juice. Your mileage may vary.

"double clicks every single time i press it"

This issue usually has a fairly easy way to fix this. Logitech uses omniswitches, just open the switch and flatten the click button. It really isn't that hard, you can look for some tutorials on youtube.

If you're decided on buying a new one, Logitech cables are mostly braided and you can tape it to your desk while giving some head room for the cable. It shouldn't be much of a problem.

You can also put the cable below something like a speaker, mine looks like this;

Before buying a new mouse I'd recommend just taking a screwdriver and trying to fix it. You don't have any warranty left after 4 years, so what's to lose?

Open the mouse, take it apart gently. Open the buggy switch, just bend the little metal thingy, reassemble and you"re probably good to go. Just look on youtube how to open the switches and what to bend. I fixed multiple mice that way.

In case that doesn't work you could get some new switches for like 5 bucks. Then find someone to desolder the old one and put in a new one.

Or well. Throw away a perfectly good mouse and buy a new one for 90$. Your choice.

I assume you have checked if it is double click settings, static charge or driver so have you tried this? I once used it for a few years to avoid the cost of a new mouse.

That said for desktop corded generally works well enough, it is for laptops that the difference is huge.

the left click on my G502 died in a few months I didn't even bother RMAing it, just bought another non logitech mouse, I've had enough of their 'quality' products (it was the third logitech mouse that died on me in a relatively short time)

Not at all. Every mouse should have a tail. ;)

It really depends on your desk configuration and kind of clutter you usually have around your computer. If you have enough space for the cord to lie without interfering with anything when you move the mouse, I'd wager you wouldn't notice much difference if at all. I'd also say that mouse shape and button layout will take more getting used to than having a cord.
Now with all that said if your mouse is otherwise fine in terms of wear and tear I strongly recommend fixing it because that just sounds like old worn out microswitches and the mouse should work for another 4 years if not more. If going to a repair shop for a simple switch replacement is not an option due to quarantine or other reasons, you can try this fix: https://www.instructables.com/id/Repair-mouse-with-double-click-problem/ There's no soldering involved, but it's VERY fiddly to put the flat spring back into the switch. I personally used this method on several mice including my personal one (G9x too :)) and it still works 4 years later, though I had to repeat the procedure about 18 months after the first time. But that's not for everyone since fitting the tiny flat spring back in can be a pain.
There's a guide on fixing G602 specifically https://www.youtube.com/watch?v=EU8Zzn0oxMQ although it's not a very good one it can give you good idea whether it's something you'd be comfortable trying or not.

[I feel your pain, as ffter 5+ years of hard use, my logitech m560 is trying to bite the dust. As a result, I've spent the last 6 months looking and wondering myself. ;-) ]
I am seriously and strongly considering at the g602 or the upgraded g604. I'd recommend you check out the g604, as it adds the option of bluetooth capability + a tilting wheel but it is otherwise similar to the g602.
I'm also considering the Corsair Dark Core (non-SE) mouse, but it lacks the tilt wheel, which I use literally daily. Consider this, as it goes on sale about $60 USD. However, it does lack storage for the dongle, which is a big plus for logitech mice.

If the price is reasonable, the G502 also comes in a wireless format.

Not to derail the topic, but if anyone knows if the g604 bluetooth does indeed work with win 7 pro, this knowledge would be appreciated.

Well all.

I tried for 2 hours to put the metal part back in as videos show (well not show they bloody edit that bit out for some reason, the only own who does show how to do do it has the switch in his hand not a switch mounted between a scroll wheel and the 2 side switches). After 2 hours it was together again and didn't click at all. Took it out, tried to reseat it for an hour, and then it broke but was so bent out of shape I doubt it would ever work. All this money on mouses and its all down to a bit of tin foil.

Tomorrow I will go get the Hero 502.
