Hi5, got the same from a different seller.
Dont buy these cheap Amazon no-name mice. The sensor, switches, cable, etc. are all generally crap.
Logitech, Zowie, Steelseries and Razer alo g with a few other established brands are really all you should look at unless you ABSOLUTELY need to pinch pennies. Its an extremely noticable difference.
If ypu need advice on choosing check out “Rocket Jump Ninja” on Youtube and reddit.com/r/mousereview
Oh boy. Don’t go on r/mechanicalkeyboards and don’t search Rocket Jump Ninja.
They are going to drain your wallet, like this forum does 
But They™ did.
Turns out it was a scam...
"Your recent eBay transaction may be from a compromised account"
This one looks super legit.
EDIT:
I would create a deal alert thread, but there's only one left.
UPDATE:
Someone snagged the other one.
I received the Logitech G502 today.
It's very nice, but it'll take a while before I'm completely used to it.
I'm glad I paid $30 instead what it usually costs, $50.
I have two computers, so if I fall in love with it, I might pick up another one for Black Friday/Cyber Monday.

My mouse of choice has been the Logitech G502 for a while now.
I got one for my mom, but she dropped it a few times, and now it doesn’t work correctly.
She wants a different mouse, so I did some research.
She wants a mouse that is inexpensive, and with as not so many buttons.
(The Logitech G502 has too many buttons for her, even though I disabled the buttons that she doesn’t like.)
Unfortunately, nice computer mice with a DPI switch seem to always have a back and forward button, so that’s what I ordered for her (even though she doesn’t like back and forward buttons.)
This is what I ordered yesterday…

The mouse’s lighting can be disabled.
This mouse is similar to another mouse that my mom used to have, and she liked that one.
(The general design of this mouse is quite common, with a number of clones available online.)
In about a week, we should know if this mouse is good enough for her.
The gaming mouse arrived today.
The DPI buttons do not change the DPI.
My mom doesn’t really care about that, and otherwise the mouse is quite nice for the money.
I’ll stick with my Logitech G502 gaming mice, but this inexpensive gaming mouse seems to be good enough for my mom. 
I’m Logitech G502 fan and have a couple of spares.
A while back I had one with the famous double issue and logitech sent me a replacement and didn’t even want me to send back the original.
I had to save this guide for future use if I ever run into issues with the switch, I think you can swap it out for a quieter and smooth switch. https://old.reddit.com/r/MouseReview/comments/aksjr6/g502_switch_replacement_guide_highres/
Tried and own so many miceses but my best one is the Swiftpoint Z2
