I can vouch for this as well. I bought 2 expensive mechanical keyboards that would disconnect randomly, repeat keys, and even press keys that were somewhat near other keys I pressed. That and their Razer Synapse software is terrible. It's bloated, it fails to update sometimes and I had other problems with it. Even the fucking mousepad I bought from them doesn't work correctly, I had to use double-sided tape to stop it from sliding everywhere!
I've since wised up and stopped giving them my money.
