6 second pulse delay on my Gamdias Hermes LTE Gaming Keyboard. I was not sure about this purchase but all (I can say is WOW!!!! This is a great Mechanical Gaming Keyboard... You can just t5ell when you pick it up... It has a very solid fell to it and not cheap light weight stufff... I got this with a instant -$75.00 price break for $54.99 free shipping on Newegg.... What a steal for the price.. All the keys are pressure sensitive and the WASD keys are removable...,.,... Software downloads from the manufacturer site and has great Macro options with 6 different setting groups.... The cord is a braided clothe material with gold plated USB connector for great connectivity.... As seen the keyboard pulses and has 5 different solid brightness levels and 4,6,8 second pulse delay options. The LED's are more of an orange red and not a bright apple red like I thought but still great... I can't say nothing bad about it.. It's a nice clean look without all those annoying LCD screens... Just strait to the point gaming Keyboard and would recommend it for anyone and the price is super!!!!
