Razer Synapse 2.0 blows chunks.
I own 3 Razer keyboards, 2 mice, 1 OrbWeaver and a BlackShark headset.
The BlackWidow Stealth keyboard I just purchased will be my last Razer device because I hate synapse 2.0 and the dysfunctional bloated "cloud" BS that comes with it. I just want well-made devices with no marketing gimmicks. I have been willing to tolerate the overly flashy but less than useful user interface of Synapse 2.0 because my BlackWidow Tournament keyboards and other hardware are of excellent quality (except the BlackShark headset which is too heavy and quite uncomfortable).
But that tolerance has ended after I plugged in my new BlackWidow Stealth and have been waiting hours for Synapse 2.0 to download a software update in order to user it. I am a software engineer and sysadmin, and it looks like either Razer's servers are overloaded, screwed, or experiencing a DDoS attack. In any case, they are 100% culpable for inserting a completely unnecessary dependency on their network infrastructure to download a HUGE bloatware app just to use a freakin keyboard.
Razer: if you don't include a DVD then your server infrastructure must be stable and able to cope with the load or DDoS attacks, or whatever is going on.
To add insult to injury, the update app says "do not disconnect any Razer devices or restart your computer until the update finishes"
THERE SHOULD BE A "cancel" BUTTON if the update has a potential to take 5 hours.
