Review on Logitech Cordless Revolution Bluetooth Keyboard by Mateusz Grzesiak  (M ᠌

Reviews for this kit are quite contradictory. (Now I'll explain why!) After the initial installation, noticeable lags were observed (i. E., the mouse slowed down, sometimes even the keyboard . this is of course a fraction of a second, but it really annoyed . the sensations are something like this: as if on a single-processor computer, the load is 100% . generally forgotten already, I must say, such feelings). Well, I think for that kind of money. it's just the audacity to put such a product on sale. after a short search on the Internet, it turned out. that other devices can affect the signal transmitted via bluetooth. including even an Ethernet cable , i. E. there is a place to be all sorts of interference . shifted the bluetooth receiver to another place away from other wires. The lags/brakes are gone! But! The mouse still has poor positioning accuracy (i. E. controllability, I don’t know how to call it correctly) . this can be due to two factors: - either the resolution of the laser sensor is not very good, - either the bluetooth ate rate is too low, - I do not rule out that both of these factors together affect the quality of management. You will not believe, but my old wired laser mouse for 500r. though 2500dpi works really better - it is much more manageable (and I was going to throw it away))) And one more important point - I'm not a gamer. I’m not crazy about razers . I took it purely for design work (photoshop, illustrator, etc.) I thought getting rid of the wires would make life easier and more pleasant :) how wrong I was))) I took this kit for my DR. As a result, when I decided to return it back, and it was the very next day, I was really nervous, because I thought that they would not return the money back. And there is no desire to stay with such a device for such money.
