Mouse Razer + 3000 to a sense of elitism - 3000 k from the wallet. I am glad that there are two additional buttons, for DPI, however, you can bind them to anything. Battery power can be attributed to both pluses and minuses. On the one hand, it can last forever, since the native battery will never die (and there will be no need to replace s), on the other hand, you will have to spend money on batteries or buy batteries with a charger, which also could not be wasted. With AA battery (included), a very strong advantage on the backside. I'm not a pro gamer for a long time, but I don't like it too much, using it like that is not an option at all, it's not about weight, it's about balance. More or less normal balance only with AAA battery. Although the advantage remains, it is no longer so significant and is more or less in balance. Despite the reviews, the 1.2v battery ate at 950 mha from the GP, Razer's software does not complain about the discharge. But the downside is that batteries are usually a little heavier than regular AAA batteries, although noticeably lighter than AA batteries. AA battery is not an option at all. For light weight, you need to look for low-capacity batteries with minimal weight. The batteries themselves last long enough. The complete battery for 5 days did not go even by a third with active use. The receiver in the kit is 2.4 hertz good, it hits exactly 5 meters, I didn’t check it further. The default lift height did not raise any questions. It is normal and standard for me. There is a calibration from 1 to 10 apparently millimeters. The right key has more travel than the left. Probably right, but some people say it's unpleasant because of such a slight backlash before pressing. Conclusions. Took for 3k. Well, for 3k there and there. But the Chinese counterparts have an abundance of alternatives. You can take it if you can't live without the Dezadder form, and you definitely need wireless. I put a minus for a rattling wheel and a high price.
