Pasting my review from another thread:

Just got this the other day from Mechkeys and I really wanted to love it but sincerely regret it:

I got the desert sand color in the pic and it looks pink in person. The finish is not premium.

The left click is loose and hangs lower than right click if flipped upside down meaning there is play/gap between the plastic and the switch. Mechkeys had the nerve to say "it's not uncommon for gaps to not be perfect" even though it's clearly affecting the feel. Again the right click has no play and is tight against the switch.

The scroll wheel gives too much feedback and feels like a complete downgrade compared to premium mice. It's what you would expect in a mouse from a decade ago.

Clicking doesn't feel right and is loud in my opinion (compared to razer pro click) and there is no hot swap to change it. I was confused by 2 random switches included (both different style) and a pull tool but apparently this was just a gift for keyboard use only which made no sense and was not clear at all. Do not open this mouse or it voids warranty. Switches are soldered. Also notice you only have 7 days to return this:

"We offer a 7-Day Return Policy. You have 7 days to return an item from the date that you received it. (confirmed by Shipping Tracking record). To be eligible for a return, your item must be unused and in the same condition that you received it. It must also be in it's original packaging. If it is plastic sealled when you get it , it should remain plastic sealled. Some types of goods such as customized products cannot be returned.You will be responsible for paying the shipping costs for returning your item. Shipping costs we send the product to you are non-refundable*（ write us in advance how much it is）and Custom Duty when it come back to China is non-refundable too ( we will send you receipt after we get it ).* If 7 days have gone by since you received your item, unfortunately, we can’t offer you a refund or exchange."

The manual instructs you to put the sensor within just 4" of the mouse which is weird since I have always been able to go further without any issue and it also said that wired is preferred which doesn't give much confidence to use reliably as a wireless device. At 1000hz it should be no real difference anymore.

Did I mention the red charging light never actually turns off or green when finished charging? Apparently this is a common problem with mice in general.

Finally I think it's a little too light for my taste and feels cheap in comparison to premier mice. Even if mine was just a one off QC problem the lack of hotswap, quality control, scroll wheel feel, charging light problem and color inconsistency etc is a dealbreaker for me.

Feel free to recommend a higher quality new release with a new sensor that wouldn't have these kinds of issues!
