Haha. Lurker of Reddit mouse review so know something from lolgikek. Logitech serious out of touch when comes to gaming. From Logitech side only best selling are g pro X series and g502 series. The rest no love at all. No refresh of g703  at all after last update in 2019 (yeah I got the 2019 version g703 hero). G60x series discontinued entirely because they think cannot sell (force us to just consider razer Naga line for mmo line)

Latest g309 is just a blob of ugly mess which either use AA battery or that power mat that Malaysia never get. Oh well for g304 redesign that not really follow g304 shape

I also got m650L signature . Wtf it doesn't support multi device because lolgikek force us to buy more expensive MX just for multi device (m590 discontinued lol)

Errm, is 59 for a mouse in 2024 consider very cheap? I very long no buy mouse already

I will make sure I get my refund no matter what if the seller say opened items cannot be refunded.
How else am I going to get the serial number (which in the battery compartment) for the product registration?

haiya, some of you guys dont be so mean la..  TS,just take this as a lesson to do proper research before buying something. Yes, some peripheral do have different revision update of the same model. Altho the mystery of not able to register the other 2 mouse, have you ask the seller why?
Anyway, if this make you cant sleep at night,then continue probing the seller,else just move on. Im sure theres more things in your life to be concerned with.

Cause majority here told me to accept it as it is? :confused:

really your life in Malaysia just hang out in /k??

ask yourself if you're happy as a consumer who just bought this product and want to return then convey the same feelings to Shitpee officer.

Errm, is 59 for a mouse in 2024 consider very cheap? I very long no buy mouse already

that's why I asked him

why u need validation from strangers online when u can decide what you should do in life?

somehow I think TS gonna become that uncle who talked to himself using other dupes who kantoi by the Mod pretty soon

Mod can attest it is the other way around, you know.......

dont be like that Uncle

everyday opened new threads then talk to himself using other dupes

I guess empty nest syndrome hits him hard

My desktops and laptops don't have enough USB port for the supplied USB. If you notice the trend, these days, new mainboard and laptop "ketandusan" usb port. Hence I am making use of the Unifying functionality. Plus it is easier for me to use any one availaible mouse for every desktop and laptops I have.

Cause majority here told me to accept it as it is? :confused:

This kind of question, only you yourself can answer.

Are you satisfy with the mouse? No. Then can u get similar older model in the market? If can get and price is same, then u can ask for refund.

But if u can't get older model, then u must decide if u try other model or stick to same model. If same model, then no need refund since u can't get older model elsewhere. If u wan try other model, then just refund and buy other model.

Recently uncle decided to purchase 3 Logitech M331 during 8.8 here ALL.IT.OS

https://shopee.com.my/Logitech-M331-Silent-...9596.1019539111

After reviewing all the comment and pictures at there, uncle bought 3 M331 mices.

To uncle dismay......

[attachmentid=11501056]

Notice the problem? Uncle only received one original M331 and two fake M331. The left most is the original with LED indicator and rubberised sides. The middle and right most side are fake with no LED indicator and any rubber at all, pure plastic.

[attachmentid=11501057]

Even the bottom side is different, the original power switch is at the top, not at the bottom.

Only the original serial number is successfully registered at logitech website while the two fake failed.

Only one has Logitech Unifying functionality and successfully paired with my existing Unifying Receiver. The other two fakes can't do that.

The original M331 has this sticker with M-Link

[attachmentid=11501059]
The two fakes M331 has this sticker with MCL Bhd
Really not happy with this situation. I thought big seller like ALL.IT.OS only sells original goods and moreover, it is Shopee Mall.

Sigh, filled for refund..... RM94.34, assuming if the seller doesn't dispute it.....
edit: apparently, according to some forummer here, there is different hardware revision. Which I am still not satisfied because I don't get the functionality as advertised.
editv2: Lack of advertised "Unifying" functionality and rubberised side. Sigh....

Final edit: Sigh....as per comment from forumers here.....uncle shall cancel refund and accept it as it is.....it just that uncle feels really tired and disappointed with this "new version".

Final edit V2 :
As per recommended by some poster;
ALL IT OS, I apologize for proclaiming those two mices are fake M331, but it doesn't change the fact that the product is different than what being advertised at the store.
