a big improvement in processing quality and sensing accuracy over the msb550, but at the cost of more noise and less ergonomics. The MSB550 spoiled me with its silence and the way it fit in my hand, and I'll have a harder time with this one. Slightly less inclination and arching compared to its predecessor, reduces the ergonomics of the "semi-vertical" mouse. Not bad, but "something is missing" for 5*
I've had the Msb550 for a few months. A few falls on the ground (baby, cats) and she was gone. Ideal mouse would be MSB550 with M500 chassis. Maybe next time.
significantly better sensor than the msb550, which is very similar.
sensor located in the middle
does not wobble like msb550
decent processing, better than msb550
battery and dpi indicator (although dpi indicates the degree by the number of blinks)
a little worse ergonomics for me. It is not as ergonomically tilted to the side and is flatter than the msb550, the palm is not as relaxed in it. The buttons are higher off the ground. From the photos, I thought it was almost identical.
overall noisier than the msb550, except for the side buttons, especially the wheel press. The main buttons don't really click, rather they make a muffled hum, but they are not as quiet as their predecessor.
the side buttons should have had more resistance! Or an edge underneath to prevent accidental squeezing. They are the softest and quietest buttons on the mouse. It serves as a Back/Forward step. And you really don't want to press it by mistake while working or filling out a form.
on win10 my side scroll button in excel and browsers didn't respond, in fusion360 it behaves like the front scroll button. It has more resistance and it squeaks a bit when scrolling.
device switching should have been at the top instead of the DPI option when it is promoted as a mouse to multiple devices simultaneously.
Quite heavy and combined with the shape and smooth surface it is less comfortable when moving.
The side buttons are a big disappointment for me on an otherwise hilarious mouse. The side forward and reverse buttons don't make any sound at all and are sort of in the air and you have no feedback if you pressed the button or not. I'll try to order another piece when Alza returns the money, because otherwise it fits my hand.
the side forward and reverse buttons don't make any sound at all and are as if they are in the air and you have no feedback if you have pressed the button or not
location of the side buttons (they are too far away, but for someone with longer fingers it will be ok.

Hello, thank you for your review. The side buttons on this model are really designed with an emphasis on quiet operation without the classic response. If you're used to the classic click, their speech may seem unusual at first. However, the aim of this design is to eliminate distracting noises, especially in a quiet office environment. It is therefore not a defect but an intentional feature of the product. If necessary, please do not hesitate to contact us. Thank you and have a nice day, Ondřej - Alza expert
