Super contant (2 / 3J use)

Even if it is a product of China, it lacks the configuration software. (For certain play we just configure the two key on the dimension, if not the default navigation is / Down)
I find it great, the mode is off the light, and also the option to turn it off.
The mode automatically economy turns off after some minutes, to clik on again and responsive
The surper cool comfort it takes the shape of my hand Me, really comfortable feel of it, flat on comfort, on the rate the plastic feel is not pleasant.
A red LED indicator lights when the battery is low.
I buy without looking too closely because I needed urgently after having to buy another mouse that not walk.
In short a GOOD product, that is not the low end (just be able to make it even cheaper yet, but they view competition not going to deny it) It is anyway it! Would highly recommend.
